1. Steps to find factors of 150 using Division Method

Example: Find factors of 150

  • Divide 150 by 1: 150 ÷ 1 : Remainder = 0
  • Divide 150 by 2: 150 ÷ 2 : Remainder = 0
  • Divide 150 by 3: 150 ÷ 3 : Remainder = 0
  • Divide 150 by 5: 150 ÷ 5 : Remainder = 0
  • Divide 150 by 6: 150 ÷ 6 : Remainder = 0
  • Divide 150 by 10: 150 ÷ 10 : Remainder = 0
  • Divide 150 by 15: 150 ÷ 15 : Remainder = 0
  • Divide 150 by 25: 150 ÷ 25 : Remainder = 0
  • Divide 150 by 30: 150 ÷ 30 : Remainder = 0
  • Divide 150 by 50: 150 ÷ 50 : Remainder = 0
  • Divide 150 by 75: 150 ÷ 75 : Remainder = 0
  • Divide 150 by 150: 150 ÷ 150 : Remainder = 0

Hence, Factors of 150 are 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, and 150

2. Steps to find factors of 150 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 150 using the division method, follow these steps:

  • Step 1. Start dividing 150 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 150, which is 2. Divide 150 by 2 to obtain the quotient (75).
    150 ÷ 2 = 75
  • Step 3. Repeat step 1 with the obtained quotient (75).
    75 ÷ 3 = 25
    25 ÷ 5 = 5
    5 ÷ 5 = 1

So, the prime factorization of 150 is, 150 = 2 x 3 x 5 x 5.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 150 as shown below:

So, the prime factorization of 150 is, 150 = 2 x 3 x 5 x 5.

3. Find factors of 150 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 150 would be the two numbers which, when multiplied, give 150 as the result.

The following table represents the calculation of factors of 150 in pairs:

Factor Pair Pair Factorization
1 and 150 1 x 150 = 150
2 and 75 2 x 75 = 150
3 and 50 3 x 50 = 150
5 and 30 5 x 30 = 150
6 and 25 6 x 25 = 150
10 and 15 10 x 15 = 150

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 150. They are called negative pair factors.

Hence, the negative pairs of 150 would be ( -1 , -150 ) , ( -2 , -75 ) , ( -3 , -50 ) , ( -5 , -30 ) , ( -6 , -25 ) and ( -10 , -15 ) .

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

  • Each number is a factor of itself. Eg. 150 is a factor of itself.
  • 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, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150 are exact divisors of 150.
  • 1 is a factor of every number. Eg. 1 is a factor of 150.
  • Every number is a factor of zero (0), since 150 x 0 = 0.
