Definition of factors in math

Multiplying two whole numbers to get the original/product number and a whole number that divides exactly into another number that is called factoring.


Factors of 2 in pairs

2 has only two factors because it is a prime number, it can only be divided by 1 and itself.
We can find the Factors of 2 by multiplying two whole numbers in a pair to get the result 2.

 first: - Multiply by 1       1 × 2 = 2

 There are no more possible pairs so we have all the factors in question.
Factors pairs of 2 = (1×2)

Factorization Using Division:-

First, we divide the given number by the smallest prime number which divides the number exactly.

We can easily divide 2 by the smallest prime number 2.
 2/2 = 1
Divide the quotient again by the smallest or the next smallest prime number. We will repeat this process repeatedly until the quotient becomes (1) one.

 2 ÷ 2 = 1
