How to calculate factors in 100?
MULTIPLICATION METHOD
.First, write the number 100
.Find the two numbers, which gives the result as 100 under the multiplication, say 5 and 20, such as 5 × 20 = 100.
.We know that 5 is a prime number which has only two factors, i.e., 1 and the number itself (1 and 5) which cannot be further factorized.
5 = 5 × 1
.But look at the number 20, which is a composite number but not a prime number and it can be further factorized.
20 can be factorised as 2 x 2 x 5 x 5 x 1
.Therefore, the factorization of 100 is written as, 100 = 2 x 2 x 5 × 5 x 1
.Finally, write down all the unique numbers which we obtain from 2 x 2 x 5 × 5 x 1
FACTORS OF 100 =1,2,4,5,10,20,25,50 and 100
