Therefore, GCD of numbers 915, 404, 210 is 1

Given Input Data is 915, 404, 210

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 915 is 3 x 5 x 61

Prime Factorization of 404 is 2 x 2 x 101

Prime Factorization of 210 is 2 x 3 x 5 x 7

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(915, 404) = 369660

GCD(915, 404) = ( 915 x 404 ) / 369660

GCD(915, 404) = 369660 / 369660

GCD(915, 404) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 210

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 210) = 210

GCD(1, 210) = ( 1 x 210 ) / 210

GCD(1, 210) = 210 / 210

GCD(1, 210) = 1

GCD of 915, 404, 210 is 1
