Given Input Data is 980, 336, 715

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

Prime Factorization of 980 is 2 x 2 x 5 x 7 x 7

Prime Factorization of 336 is 2 x 2 x 2 x 2 x 3 x 7

Prime Factorization of 715 is 5 x 11 x 13

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(980, 336) = 11760

GCD(980, 336) = ( 980 x 336 ) / 11760

GCD(980, 336) = 329280 / 11760

GCD(980, 336) = 28

Step2:

Here we consider the GCD from the above i.e. 28 as first number and the next as 715

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

LCM(28, 715) = 20020

GCD(28, 715) = ( 28 x 715 ) / 20020

GCD(28, 715) = 20020 / 20020

GCD(28, 715) = 1

GCD of 980, 336, 715 is 1
