Let us suppose you have given number 240 to find the number of factors
Factor representation of 240 is
Using conventional method, you can find number of factors by manual calculation
So using this old method we can figure out that there are total 20 factors of number 240.
But this method is tedious and consumes lot of time.
Step 1: Factor representation
Step 2: Multiplication of (individual power+1)
a. Take power of all the factors
b. Add +1
c. Multiply all the numbers, you will get the answer
This way you can easily find the number of factors present in any number
