## What is the GCF for 4?

The GCF of 4 and 8 is 4. To calculate the greatest common factor of 4 and 8, we need to factor each number (factors of 4 = 1, 2, 4; factors of 8 = 1, 2, 4, 8) and choose the greatest factor that exactly divides both 4 and 8, i.e., 4.

How do you do GCF?

Here’s how to find the GCF of a set of numbers using prime factorization:

1. List the prime factors of each number.
2. Circle every common prime factor — that is, every prime factor that’s a factor of every number in the set.
3. Multiply all the circled numbers. The result is the GCF.

What are the factors of 30?

The factors of 30 are 1, 2, 3, 5, 6, 10, 15 and 30. The factors of 31 are 1 and 31. Thus, the common factor of 30 and 31 is 1 only, as 31 is a prime number.

### What is the CF and GCF of 45 and 30?

15
The GCF of 30 and 45 is 15.

### How do you find the least common multiple of 4?

The LCM of 4 and 4 is 4. To find the least common multiple of 4 and 4, we need to find the multiples of 4 (multiples of 4 = 4, 8, 12, 16, . . .) and choose the smallest multiple that is exactly divisible by 4 and 4, i.e., 4.

What is a factor of 4 and 4?
