Given Input Data is 356, 156, 815

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

Prime Factorization of 356 is 2 x 2 x 89

Prime Factorization of 156 is 2 x 2 x 3 x 13

Prime Factorization of 815 is 5 x 163

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(356, 156) = 13884

GCD(356, 156) = ( 356 x 156 ) / 13884

GCD(356, 156) = 55536 / 13884

GCD(356, 156) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 815

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

LCM(4, 815) = 3260

GCD(4, 815) = ( 4 x 815 ) / 3260

GCD(4, 815) = 3260 / 3260

GCD(4, 815) = 1

GCD of 356, 156, 815 is 1
