Find the greatest common factor of 60 and 90?

Answer 1

When you say "do" it, I'm going to assume you mean "find" it.

Here's how:

-- List all the factors of 45.

-- List all the factors of 60.

-- Compare the two lists. Boil them down to a short list of only

the numbers that appear on both lists. These are the common

factors of 45 and 60. "Common" means "same for both".

-- Find the biggest number on the short list. That's the "greatest"

common factor.

Answer 2

The GCF is 30.
the highest common factor (h.c.f) for 60 and 90 would be 30 because 2 times 30 = 60 and 30 times 3= 90

Answer 3

2 x 2 x 3 x 5 = 60

3 x 3 x 5 = 45

Select the common factors.

3 x 5 = 15, the GCF.

Answer 4

The greatest common factor of 60 and 90 is 30

Answer 5

The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question! The greatest factor of any number is itself.

Answer 6

The GCF is 30.

Answer 7
