What are Factors of 124?
Factors of 124 are pairs of those numbers whose products result in 124. These factors are either prime numbers or composite numbers.
How to Find the Factors of 124?
To find the factors of 124, we will have to find the list of numbers that would divide 124 without leaving any remainder.
- 124/2 = 62; therefore, 2 is a factor of 124 and 62 is also a factor of 124.
- 124/4 = 31; therefore, 4 is a factor of 124 and 31 is also a factor of 124.

Factors of 124 by Prime Factorization
- 124 ÷ 2 = 62
- 62 ÷ 2 = 31
Further dividing 31 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 31 by the next smallest prime factor. We stop ultimately if the next prime factor doesn't exist or when we can't divide any further.
So, the prime factorization of 124 can be written as 22 × 311 where 2, 31 are prime.
Factors of 124 in Pairs
Pair factors of 124 are the pairs of numbers that when multiplied give the product 124. The factors of 124 in pairs are:
- 1 × 124 = (1, 124)
- 2 × 62 = (2, 62)
- 4 × 31 = (4, 31)
Negative pair factors of 124 are:
- -1 × -124 = (-1, -124)
- -2 × -62 = (-2, -62)
- -4 × -31 = (-4, -31)
NOTE: If (a, b) is a pair factor of a number then (b, a) is also a pair factor of that number.
