Given number is 40 Any number that divides the given number exactly, without leaving any remainder, is known as the factor of that number. Every number is a factor of itself and 1 is the factor of every number. Write all the possible combinations for the given number starting from 1 as shown below, and continue till the factors start repeating 40 = 1 × 40 40 = 2 × 20 40 = 4 × 10 40 = 5 × 8 Thus, the factors of 40 are 1, 2 , 4, 5 , 8, 10, 20 and 40 .

Given number is 50 Any number that divides the given number exactly, without leaving any remainder, is known as the factor of that number. Every number is a factor of itself and 1 is the factor of every number. Write all the possible combinations for the given number starting from 1 as shown below, and continue till the factors start repeating 50 = 1 × 50 50 = 2 × 25 50 = 5 × 10 Thus, the factors of 50 are 1, 2 , 5, 10 , 2 5 and 50 .
