## What is the HCF of 5 and 15?

Greatest common factor (GCF) of 5 and 15 is 5..

## What’s the GCF of 15?

We found the factors and prime factorization of 15 and 25. The biggest common factor number is the GCF number. So the greatest common factor 15 and 25 is 5.

## What is the HCF of 5 10 and 15?

Factors of 15 = 1, 3, 5 and 15. Factors of 10 = 1, 2, 5 and 10. Therefore, common factor of 15 and 10 = 1 and 5. Highest common factor (H.C.F) of 15 and 10 = 5.

## What is the HCF of 15 and 30?

The common factors of 15 and 30 are 1, 3, 5, and 15. The greatest common factor is 15.

## What is the HCF of 20?

For example, find the HCF of 20 and 35. The common factors of the given numbers are : 1,2,4,5,10,20. The greatest among all other numbers is 20, so it shall be the HCF of both the numbers.

## What is the GCF of 9 and 15?

Greatest common factor (GCF) of 9 and 15 is 3.

## What is the HCF of 100?

Factors of 100 = 1, 2, 5, 10, 20, 50 and 100. Factors of 150 (one hundred fifty) =1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75 and 150. Therefore, common factor of 100 and 150 = 1, 2, 3, 5, 10 and 50. Highest common factor (H.C.F) of 900 and 270 = 50.

## What is the HCF of 12 and 15?

The factors of 12 are : 1, 2, 3, 4, 6, 12. The factors of 15 are : 1, 3, 5, 15. 1 and 3 are the only common factors (numbers which are factors of both 12 and 15). Therefore, the highest common factor of 12 and 15 is 3.

## What is the GCF of 24 and 18?

We found the factors and prime factorization of 18 and 24. The biggest common factor number is the GCF number. So the greatest common factor 18 and 24 is 6.

## What is the GCF of 12 and 30?

Earlier we found that the Common Factors of 12 and 30 are 1, 2, 3 and 6, and so the Greatest Common Factor is 6. The Greatest Common Factor of 12 and 30 is 6.

## What is the HCF of 9 15 and 24?

The GCF is the highest number that is a factor of all three of our “test subject numbers”. Ok, now let’s find what is common. There are 2s in 24 but not in 9 or 15, so there are no 2s in our GCF. There is one 3 in 24 and in 15 and two in 9 – so one 3 is common to all three numbers.

## What is the GCF of 16 and 36?

We found the factors and prime factorization of 16 and 36. The biggest common factor number is the GCF number. So the greatest common factor 16 and 36 is 4.

## What is the GCF of 9 and 18?

Greatest common factor (GCF) of 9 and 18 is 9. We will now calculate the prime factors of 9 and 18, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 9 and 18.

## What are the factors of 10 and 15?

Factor of 10 = 1, 2, 5 and 10. Factor of 15 = 1, 3, 5 and 15. Therefore, common factors of 10 and 15 = 1 and 5. 4.

## What is the greatest factor of 10?

The Greatest Common Factor (GCF) of some numbers, is the largest number that divides evenly into all of the numbers. Like, the GCF of 10,15, and 25 is 5. Type some numbers into the box to the right, and this page will find the GCF of those numbers.

## What is the GCF of 10 15 and 20?

We found the factors and prime factorization of 15 and 20. The biggest common factor number is the GCF number. So the greatest common factor 15 and 20 is 5.

## What is the HCF of 16?

Consider the highest common factor of 16 and 24 again. The common factors are 1, 2, 4 and 8. So, the highest common factor is 8.

## What is the HCF of 51?
