1. Steps to find factors of 125 using Division Method

Example: Find factors of 125

  • Divide 125 by 1: 125 ÷ 1 : Remainder = 0
  • Divide 125 by 5: 125 ÷ 5 : Remainder = 0
  • Divide 125 by 25: 125 ÷ 25 : Remainder = 0
  • Divide 125 by 125: 125 ÷ 125 : Remainder = 0

Hence, Factors of 125 are 1, 5, 25, and 125

2. Steps to find factors of 125 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 125 using the division method, follow these steps:

  • Step 1. Start dividing 125 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 125, which is 5. Divide 125 by 5 to obtain the quotient (25).
    125 ÷ 5 = 25
  • Step 3. Repeat step 1 with the obtained quotient (25).
    25 ÷ 5 = 5
    5 ÷ 5 = 1

So, the prime factorization of 125 is, 125 = 5 x 5 x 5.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 125 as shown below:

So, the prime factorization of 125 is, 125 = 5 x 5 x 5.

3. Find factors of 125 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 125 would be the two numbers which, when multiplied, give 125 as the result.

The following table represents the calculation of factors of 125 in pairs:

Factor Pair Pair Factorization
1 and 125 1 x 125 = 125
5 and 25 5 x 25 = 125

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 125. They are called negative pair factors.

Hence, the negative pairs of 125 would be ( -1 , -125 ) , ( -5 , -25 ) .

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 factor of a number is an exact divisor of that number, example 1, 5, 25, 125 are exact divisors of 125.
  • Every number other than 1 has at least two factors, namely the number itself and 1.
  • Each number is a factor of itself. Eg. 125 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 125.
