What is the greatest common factor of 4?
The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of
12, 20, and 24
is 4.
How do you know if a number is a factor of 4?
Divisibility Rules
If a number ends with a 0 or a 5, it’s divisible by 5, i.e. 5 is a factor.
If a number is divisible twice by 2, it’s divisible by 4
, i.e. 4 is a factor.

What is the HCF of 6 18 and 24?
Correct answer:
The greatest common factor is the greatest factor that divides both numbers. To find the greatest common factor, first list the prime factors of each number. 18 and 24 share one 2 and one 3 in common. We multiply them to get the GCF, so
2 * 3 = 6
is the GCF of 18 and 24.
What is the HCF for 18 and 24?
What is the HCF of 18 and 24? The HCF of 18 and 24 is
6
