Factors of 162 that add upto 21

Steps to find factors of 162 that add upto 21

• Find all factors.
• Then we find the sum of combinations of factors.
• Note down the combination of factors with sum as 21, and read off the answer!

Steps to find Factors of 162

• Step 1. Find all the numbers that would divide 162 without leaving any remainder. Starting with the number 1 upto 81 (half of 162). The number 1 and the number itself are always factors of the given number.
  162 ÷ 1 : Remainder = 0

  162 ÷ 2 : Remainder = 0

  162 ÷ 3 : Remainder = 0

  162 ÷ 6 : Remainder = 0

  162 ÷ 9 : Remainder = 0

  162 ÷ 18 : Remainder = 0

  162 ÷ 27 : Remainder = 0

  162 ÷ 54 : Remainder = 0

  162 ÷ 81 : Remainder = 0

  162 ÷ 162 : Remainder = 0

Hence, Factors of 162 are 1, 2, 3, 6, 9, 18, 27, 54, 81, and 162

How do you explain factors?

In mathematics, the term factor is a number or an algebraic expression that divides another number or an expression completely without leaving any remainder. A factor of a number can be positive or negative.

Properties of Factors

• Each number is a factor of itself. Eg. 162 is a factor of itself.
• 2 is the only even prime factor any number can have.
• Every factor of a number is an exact divisor of that number, example 1, 2, 3, 6, 9, 18, 27, 54, 81, 162 are exact divisors of 162.
• 1 is the common and smallest natural factor every number can have.
• Every number is a factor of zero (0), since 162 x 0 = 0.
