LCM of 9 and 15 and the GCF 9 and 15

What is the GCF and LCM of 9 15?

When trying to find the greatest common factor (GCF) and least common multiple (LCM) of two numbers, 9 and 15, it is important to list out the factors of each number. The factors of 9 are 1, 3, and 9, and the factors of 15 are 1, 3, 5, and 15. The greatest common factor of 9 and 15 is 3, and the least common multiple is 45.

What’s the greatest common factor of 15?

The greatest common factor of 15 is 3. This is because 3 is the largest number that can evenly divide into 15. To find the greatest common factor of two numbers, you can use the prime factorization method.

This involves writing out the prime factorization of each number and then finding the largest number that is common to both. For 15, the prime factorization is 3 x 5. For 18, the prime factorization is 2 x 3 x 3.

The largest number that is common to both is 3, so the greatest common factor is 3.

What is the greatest common factor of 20 and 15?

The greatest common factor of 20 and 15 is 5. This is because 5 is the largest number that can go into both 20 and 15 evenly. To find the greatest common factor of two numbers, you can either list out the factors of each number and then find the largest number that appears on both lists, or you can use the greatest common factor formula.

What is the lcm of 9 and 15

The lowest common multiple (LCM) of two integers is the smallest integer that is evenly divisible by both numbers. In mathematics, the least common multiple, lowest common multiple, or smallest common multiple of two integers a and b, usually denoted by LCM(a, b), is the smallest positive integer that is divisible by both a and b. For example, the LCM of 15 and 9 is 45.

What is the greatest common factor of 10 and 25

The greatest common factor (GCF) of 10 and 25 is 5. To find the GCF of two numbers, you can use the prime factorization method. This involves finding the prime factorization of each number and then finding the largest number that is common to both lists.

In this case, the prime factorization of 10 is 2 * 5 and the prime factorization of 25 is 5 * 5. The largest number that is common to both lists is 5, so the GCF is 5.

Common factor of 4 and 15

When two numbers have a common factor, it means that they can both be divided by a certain number. The common factor of 4 and 15 is 3. This is because 3 can be evenly divided into both 4 and 15.

When finding the common factor of two numbers, you must first list the factors of each number. The factors of 4 are 1, 2, and 4. The factors of 15 are 1, 3, 5, and 15.

As you can see, 3 is the only number that appears on both lists. Therefore, 3 is the common factor of 4 and 15.

Common factors of 7 and 14

When looking at the factors of 7 and 14, there are some that are common between the two numbers. The first common factor is 1. Every number has a factor of 1.

The next common factor is 7. 7 is a factor of both 7 and 14. The next common factor is 2.

2 is a factor of 14, but not of 7. The next common factor is 14. 14 is a factor of both 7 and 14.

The last common factor is 7. 7 is a factor of both 7 and 14.

Gcf of 9 and 36

The greatest common factor (GCF) of 9 and 36 is 9. To find the GCF of 9 and 36, we can use the prime factorization method. The prime factorization of 9 is 3 x 3 and the prime factorization of 36 is 2 x 2 x 3 x 3.

Since both 9 and 36 have a factor of 3, we know that 3 is a common factor between the two numbers. However, since 9 also has a factor of 3, we know that 3 is the greatest common factor between 9 and 36.

Highest common factor of 6 and 24

The highest common factor (HCF) of 6 and 24 is 6. To find the HCF of two or more numbers, you need to find the largest number that is a factor of all the numbers. Factors are numbers that can be multiplied together to produce another number.

For example, the factors of 6 are 1, 2, 3 and 6. The highest common factor of 6 and 24 is 6 because it is the largest number that is a factor of both 6 and 24. To find the HCF of 6 and 24, you can list the factors of each number and then find the largest number that is common to both lists.

The factors of 6 are 1, 2, 3 and 6. The factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24. The highest common factor of 6 and 24 is 6.

Gcf of 12 and 18

When two numbers have a greatest common factor (GCF), it means that they share a common factor. The GCF of 12 and 18 is 6. This is because 6 is the largest number that both 12 and 18 can be divided by evenly.

To find the GCF of two numbers, you can use the Prime Factorization Method. This involves writing out the prime factorization of each number and finding the largest number that is common to both. For 12, the prime factorization is 2 x 2 x 3.

For 18, the prime factorization is 2 x 3 x 3. The largest number that is common to both is 3, so the GCF is 3. You can also use the Euclidean Algorithm to find the GCF of two numbers.

This is a more complicated method, but it can be useful if you don’t know the prime factorization of one or both of the numbers.

Conclusion

The greatest common factor of 9 and 15 is 3.
