Steps to find factors of 165 in pair

Example: Find factors of 165 in pair

Factor Pair Pair Factorization
1 and 165 1 x 165 = 165
3 and 55 3 x 55 = 165
5 and 33 5 x 33 = 165
11 and 15 11 x 15 = 165

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 165. They are called negative pair factors.

Hence, the negative pairs of 165 would be ( -1 , -165 ) .

Definition of factor pairs?

In mathematics, factor pair are often given as pair of numbers which when multiplied together give the original number. Every natural number is a product of atleast one factor pair. Eg- Factors of 165 are 1 , 3 , 5 , 11 , 15 , 33 , 55 , 165. So, factors of 165 in pair are (1,165), (3,55), (5,33), (11,15).

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

  • Every factor of a number is an exact divisor of that number, example 1, 3, 5, 11, 15, 33, 55, 165 are exact divisors of 165.
  • Every number other than 1 has at least two factors, namely the number itself and 1.
  • Each number is a factor of itself. Eg. 165 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 165.

Steps to find Factors of 165

  • Step 1. Find all the numbers that would divide 165 without leaving any remainder. Starting with the number 1 upto 82 (half of 165). The number 1 and the number itself are always factors of the given number.
    165 ÷ 1 : Remainder = 0
    165 ÷ 3 : Remainder = 0
    165 ÷ 5 : Remainder = 0
    165 ÷ 11 : Remainder = 0
    165 ÷ 15 : Remainder = 0
    165 ÷ 33 : Remainder = 0
    165 ÷ 55 : Remainder = 0
    165 ÷ 165 : Remainder = 0

Hence, Factors of 165 are 1, 3, 5, 11, 15, 33, 55, and 165
