Knowing the factors of 4 will help you solve many maths problems. What are the factors? They are just the specific digits that divide the number equally leaving no remainders. Let us not waste the time and jump to learn the numbers that are factors of 4.

**What Are The Factors Of 4?**

1, 2, 4 are factors of 4. The factor numbers are those specific numbers that divide the given digit in such a way that there will be no remainder left.

So all factors of 4 are 1, 2, 4. Now

- 1(4➗1=4)
- 2(4➗2=2)
- 4(4➗4=1)

1, 2, 4 are factors for 4.

After knowing what all the factors of 4 are let us know more about the 4 factors

**Prime Factors Of 4**

To know the prime factors of 4, first, you should know the prime numbers up to 4. After that, we have to divide 4 by all prime numbers. Now, we will see the prime factors by factorization method.

- 4➗2 = 2
- 4➗3 = 1.33

So the prime factor for the number 4 is 2 and 3

**Factors Of 4 In Pairs**

The product of the number whose result will be 4, that number is nothing but the pair factors of 4.

So the pair factors of 4 are

- 1 and 4 (1 x 4 = 4 & 4 x 1 = 4)
- 2 and 2 (2 x 2 = 4)

**Factors Of -4**

The negative numbers of factors of 4 are called factors of -4.

Below You can see the numbers.

- -1(-4➗-1=-4)
- -2(-4➗-2=-2)
- -4(-4➗-4=-1)

The Factors for -4 are -1, -2, -4
