How to Find the Factors of 115?

To find the factors of 115, we will have to find the list of numbers that would divide 115 without leaving any remainder.

• 115/23 = 5; therefore, 23 is a factor of 115 and 5 is also a factor of 115.
• 115/115 = 1; therefore, 115 is a factor of 115 and 1 is also a factor of 115.

Similarly we can find other factors. Hence, the factors of 115 are 1, 5, 23, 115.

• Factors of 78 - The factors of 78 are 1, 2, 3, 6, 13, 26, 39, 78
• Factors of 19 - The factors of 19 are 1, 19
• Factors of 75 - The factors of 75 are 1, 3, 5, 15, 25, 75

The number 115 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 115. The first step is to divide the number 115 with the smallest prime factor, here it is 5. We keep dividing until it gives a non-zero remainder.

• 115 ÷ 5 = 23

Further dividing 23 by 5 gives a non-zero remainder. So we stop the process and continue dividing the number 23 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 115 can be written as 5¹ × 23¹ where 5, 23 are prime.

Pair factors of 115 are the pairs of numbers that when multiplied give the product 115. The factors of 115 in pairs are:

• 1 × 115 = (1, 115)
• 5 × 23 = (5, 23)

Negative pair factors of 115 are:

• -1 × -115 = (-1, -115)
• -5 × -23 = (-5, -23)

NOTE: If (a, b) is a pair factor of a number then (b, a) is also a pair factor of that number.
