What are Factors of 442?
Factors of 442 are pairs of those numbers whose products result in 442. These factors are either prime numbers or composite numbers.
How to Find the Factors of 442?
To find the factors of 442, we will have to find the list of numbers that would divide 442 without leaving any remainder.
- 442/13 = 34; therefore, 13 is a factor of 442 and 34 is also a factor of 442.
- 442/2 = 221; therefore, 2 is a factor of 442 and 221 is also a factor of 442.

Factors of 442 by Prime Factorization
- 442 ÷ 2 = 221
Further dividing 221 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 221 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 442 can be written as 21 × 131 × 171 where 2, 13, 17 are prime.
Factors of 442 in Pairs
Pair factors of 442 are the pairs of numbers that when multiplied give the product 442. The factors of 442 in pairs are:
- 1 × 442 = (1, 442)
- 2 × 221 = (2, 221)
- 13 × 34 = (13, 34)
- 17 × 26 = (17, 26)
Negative pair factors of 442 are:
- -1 × -442 = (-1, -442)
- -2 × -221 = (-2, -221)
- -13 × -34 = (-13, -34)
- -17 × -26 = (-17, -26)
NOTE: If (a, b) is a pair factor of a number then (b, a) is also a pair factor of that number.
