What is the GCF of 10 and 15?

Greatest common factor (GCF) of 10 and 15 is 5. We will now calculate the prime factors of 10 and 15, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 10 and 15.

How do you solve for GCF?

The greatest common factor, or GCF, is the greatest factor that divides two numbers. To find the GCF of two numbers: List the prime factors of each number. Multiply those factors both numbers have in common.

What is the GCF of 15 and 45?

Greatest common factor (GCF) of 15 and 45 is 15.

What is the GCF of 15 and 18?

The factors of 18 are 18, 9, 6, 3, 2, 1. The common factors of 15 and 18 are 3, 1, intersecting the two sets above. In the intersection factors of 15 ∩ factors of 18 the greatest element is 3. Therefore, the greatest common factor of 15 and 18 is 3.

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 HCF for 15 and 45?

The factors of 45 are 45, 15, 9, 5, 3, 1. The common factors of 15 and 45 are 15, 5, 3, 1, intersecting the two sets above. In the intersection factors of 15 ∩ factors of 45 the greatest element is 15. Therefore, the greatest common factor of 15 and 45 is 15.

What’s the GCF of 32 and 36?
