 # Factors of 4

Factors of 4 are the numbers that divide the original number completely or uniformly. The two numbers which when gets multiplied and gives the result the original number, are termed as pair factors.

 Factors of 4 = 1, 2 and 4

We will use the same factorization method to find the factors and multiples of 4.

In this method we need to first consider the number itself and one as the factors, so 4 and 1 are the factors of 4 and then keep finding the factors of 4 which shall give us the number 4.

## Pair Factors of 4

To find the pair factors of 4, multiply the 2 numbers in a pair to have the original numbers as 17, such numbers are as follows:

(1, 4)

(2, 2)

These above are the positive pair factors for 4.

### Factor of 4 in pairs

(1, 4) are the factors of 4 as 1 x 4 is 4.

(2, 2) are the factors of 4 as 2 x 2 is 4.

So the factors of 4 are 1, 2, 4

### Prime Factors of 4

The prime factorisation of 4 gives:

4 = 1 x 2 x 2 = 22
