Given Input Data is 352, 392, 815

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

Prime Factorization of 352 is 2 x 2 x 2 x 2 x 2 x 11

Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7

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(352, 392) = 17248

GCD(352, 392) = ( 352 x 392 ) / 17248

GCD(352, 392) = 137984 / 17248

GCD(352, 392) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 815

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

LCM(8, 815) = 6520

GCD(8, 815) = ( 8 x 815 ) / 6520

GCD(8, 815) = 6520 / 6520

GCD(8, 815) = 1

GCD of 352, 392, 815 is 1
