Factors of 515 by Prime Factorization
 515 ÷ 5 = 103
Further dividing 103 by 5 gives a nonzero remainder. So we stop the process and continue dividing the number 103 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 515 can be written as 5^{1} × 103^{1} where 5, 103 are prime.
Factors of 515 in Pairs
Pair factors of 515 are the pairs of numbers that when multiplied give the product 515. The factors of 515 in pairs are:
 1 × 515 = (1, 515)
 5 × 103 = (5, 103)
Negative pair factors of 515 are:
 1 × 515 = (1, 515)
 5 × 103 = (5, 103)
NOTE: If (a, b) is a pair factor of a number then (b, a) is also a pair factor of that number.
