What are Factors of 248?
Factors of 248 are pairs of those numbers whose products result in 248. These factors are either prime numbers or composite numbers.
How to Find the Factors of 248?
To find the factors of 248, we will have to find the list of numbers that would divide 248 without leaving any remainder.
- 248/31 = 8; therefore, 31 is a factor of 248 and 8 is also a factor of 248.
- 248/2 = 124; therefore, 2 is a factor of 248 and 124 is also a factor of 248.

Factors of 248 by Prime Factorization
- 248 ÷ 2 = 124
- 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 248 can be written as 23 × 311 where 2, 31 are prime.
Factors of 248 in Pairs
Pair factors of 248 are the pairs of numbers that when multiplied give the product 248. The factors of 248 in pairs are:
- 1 × 248 = (1, 248)
- 2 × 124 = (2, 124)
- 4 × 62 = (4, 62)
- 8 × 31 = (8, 31)
Negative pair factors of 248 are:
- -1 × -248 = (-1, -248)
- -2 × -124 = (-2, -124)
- -4 × -62 = (-4, -62)
- -8 × -31 = (-8, -31)
NOTE: If (a, b) is a pair factor of a number then (b, a) is also a pair factor of that number.
