Factors of 788 by Prime Factorization
- 788 ÷ 2 = 394
- 394 ÷ 2 = 197
Further dividing 197 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 197 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 788 can be written as 22 × 1971 where 2, 197 are prime.
Factors of 788 in Pairs
Pair factors of 788 are the pairs of numbers that when multiplied give the product 788. The factors of 788 in pairs are:
- 1 × 788 = (1, 788)
- 2 × 394 = (2, 394)
- 4 × 197 = (4, 197)
Negative pair factors of 788 are:
- -1 × -788 = (-1, -788)
- -2 × -394 = (-2, -394)
- -4 × -197 = (-4, -197)
NOTE: If (a, b) is a pair factor of a number then (b, a) is also a pair factor of that number.
