How to Find the Factors of 655?

To find the factors of 655, we will have to find the list of numbers that would divide 655 without leaving any remainder.

• 655/5 = 131; therefore, 5 is a factor of 655 and 131 is also a factor of 655.
• 655/1 = 655; therefore, 1 is a factor of 655 and 655 is also a factor of 655.

Similarly we can find other factors. Hence, the factors of 655 are 1, 5, 131, 655.

• Factors of 34 - The factors of 34 are 1, 2, 17, 34
• Factors of 55 - The factors of 55 are 1, 5, 11, 55
• Factors of 16 - The factors of 16 are 1, 2, 4, 8, 16
• Factors of 66 - The factors of 66 are 1, 2, 3, 6, 11, 22, 33, 66

The number 655 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 655. The first step is to divide the number 655 with the smallest prime factor, here it is 5. We keep dividing until it gives a non-zero remainder.

• 655 ÷ 5 = 131

Further dividing 131 by 5 gives a non-zero remainder. So we stop the process and continue dividing the number 131 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 655 can be written as 5¹ × 131¹ where 5, 131 are prime.

Pair factors of 655 are the pairs of numbers that when multiplied give the product 655. The factors of 655 in pairs are:

• 1 × 655 = (1, 655)
• 5 × 131 = (5, 131)

Negative pair factors of 655 are:

• -1 × -655 = (-1, -655)
• -5 × -131 = (-5, -131)

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