Steps to find Factors of 18

Step 1. Find all the numbers that would divide 18 without leaving any remainder. Starting with the number 1 upto 9 (half of 18). The number 1 and the number itself are always factors of the given number.

18 ÷ 1 : Remainder = 0

18 ÷ 2 : Remainder = 0

18 ÷ 3 : Remainder = 0

18 ÷ 6 : Remainder = 0

18 ÷ 9 : Remainder = 0

18 ÷ 18 : Remainder = 0

Hence, Factors of 18 are 1, 2, 3, 6, 9, and 18
