Steps to find Factors of 90

Step 1. Find all the numbers that would divide 90 without leaving any remainder. Starting with the number 1 upto 45 (half of 90). The number 1 and the number itself are always factors of the given number.

90 ÷ 1 : Remainder = 0

90 ÷ 2 : Remainder = 0

90 ÷ 3 : Remainder = 0

90 ÷ 5 : Remainder = 0

90 ÷ 6 : Remainder = 0

90 ÷ 9 : Remainder = 0

90 ÷ 10 : Remainder = 0

90 ÷ 15 : Remainder = 0

90 ÷ 18 : Remainder = 0

90 ÷ 30 : Remainder = 0

90 ÷ 45 : Remainder = 0

90 ÷ 90 : Remainder = 0

Hence, Factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90

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. 90 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, 5, 6, 9, 10, 15, 18, 30, 45, 90 are exact divisors of 90.
1 is the common and smallest natural factor every number can have.
Every number is a factor of zero (0), since 90 x 0 = 0.
