Given Input Data is 351, 147, 691

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

Prime Factorization of 351 is 3 x 3 x 3 x 13

Prime Factorization of 147 is 3 x 7 x 7

Prime Factorization of 691 is 691

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(351, 147) = 17199

GCD(351, 147) = ( 351 x 147 ) / 17199

GCD(351, 147) = 51597 / 17199

GCD(351, 147) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 691

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

LCM(3, 691) = 2073

GCD(3, 691) = ( 3 x 691 ) / 2073

GCD(3, 691) = 2073 / 2073

GCD(3, 691) = 1

GCD of 351, 147, 691 is 1
