What are Factors of 242?
Factors of 242 are pairs of those numbers whose products result in 242. These factors are either prime numbers or composite numbers.
How to Find the Factors of 242?
To find the factors of 242, we will have to find the list of numbers that would divide 242 without leaving any remainder.
- 242/22 = 11; therefore, 22 is a factor of 242 and 11 is also a factor of 242.
- 242/121 = 2; therefore, 121 is a factor of 242 and 2 is also a factor of 242.

Factors of 242 by Prime Factorization
- 242 ÷ 2 = 121
Further dividing 121 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 121 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 242 can be written as 21 × 112 where 2, 11 are prime.
Factors of 242 in Pairs
Pair factors of 242 are the pairs of numbers that when multiplied give the product 242. The factors of 242 in pairs are:
- 1 × 242 = (1, 242)
- 2 × 121 = (2, 121)
- 11 × 22 = (11, 22)
Negative pair factors of 242 are:
- -1 × -242 = (-1, -242)
- -2 × -121 = (-2, -121)
- -11 × -22 = (-11, -22)
NOTE: If (a, b) is a pair factor of a number then (b, a) is also a pair factor of that number.
