Factors of 4

The two numbers which when gets multiplied and gives the result as 4, then these numbers are called the factors of 4.

These numbers can be positive or negative but shall not be in decimal form or fractions. Let’s take an example to understand this concept. The factor pairs for number 31 will be

(1, 31) (-1, -31)

When we multiply the factors (1, 31) we get the number 31.

In the same way, even when we multiply the two negative factors(-1, -31) then we get the number 31 only.

So, we can say that both positive and negative factors pairs of 31 are the factors of 31. 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 is the factors of 4 and then keep finding the factors of 4 which shall give us the number 4.

Prime Pair Factors of 4

To find the pair factors of 4, multiply the 2 no.s in a pair to have the original numbers as 17, such numbers are as follows:

(1, 4)

(2, 2)

(4, 1)

These above are the positive pair factors for 4.

Prime Factors of 4

These are the negative pair factors for 4.

(-1, -4)

(-2, -2)

(-4, -1)

Factor of 4 in pairs

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

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

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

So the factors of 4 are 1, 2, 4
