1. Steps to find factors of 655 using Division Method

Example: Find factors of 655

  • Divide 655 by 1: 655 ÷ 1 : Remainder = 0
  • Divide 655 by 5: 655 ÷ 5 : Remainder = 0
  • Divide 655 by 131: 655 ÷ 131 : Remainder = 0
  • Divide 655 by 655: 655 ÷ 655 : Remainder = 0

Hence, Factors of 655 are 1, 5, 131, and 655

2. Steps to find factors of 655 using Prime Factorization

A prime number is a number that has exactly two factors, 1 and the number itself. Prime factorization of a number means breaking down of the number into the form of products of its prime factors.

There are two different methods that can be used for the prime factorization.

Method 1: Division Method

To find the primefactors of 655 using the division method, follow these steps:

  • Step 1. Start dividing 655 by the smallest prime number, i.e., 2, 3, 5, and so on. Find the smallest prime factor of the number.
  • Step 2. After finding the smallest prime factor of the number 655, which is 5. Divide 655 by 5 to obtain the quotient (131).
    655 ÷ 5 = 131
  • Step 3. Repeat step 1 with the obtained quotient (131).
    131 ÷ 131 = 1

So, the prime factorization of 655 is, 655 = 5 x 131.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 655 as shown below:

So, the prime factorization of 655 is, 655 = 5 x 131.

3. Find factors of 655 in Pairs

Pair factors of a number are any two numbers which, which on multiplying together, give that number as a result. The pair factors of 655 would be the two numbers which, when multiplied, give 655 as the result.

The following table represents the calculation of factors of 655 in pairs:

Factor Pair Pair Factorization
1 and 655 1 x 655 = 655
5 and 131 5 x 131 = 655

Since the product of two negative numbers gives a positive number, the product of the negative values of both the numbers in a pair factor will also give 655. They are called negative pair factors.

Hence, the negative pairs of 655 would be ( -1 , -655 ) , ( -5 , -131 ) .

What are factors?

In mathematics, a factor is that number which divides into another number exactly, without leaving a remainder. A factor of a number can be positive or negative.

Properties of factors

  • Every number is a factor of zero (0), since 655 x 0 = 0.
  • Every number other than 1 has at least two factors, namely the number itself and 1.
  • Every factor of a number is an exact divisor of that number, example 1, 5, 131, 655 are exact divisors of 655.
  • Factors of 655 are 1, 5, 131, 655. Each factor divides 655 without leaving a remainder.
