Therefore, GCD of numbers 778, 987, 246 is 1

Given Input Data is 778, 987, 246

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

Prime Factorization of 778 is 2 x 389

Prime Factorization of 987 is 3 x 7 x 47

Prime Factorization of 246 is 2 x 3 x 41

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(778, 987) = 767886

GCD(778, 987) = ( 778 x 987 ) / 767886

GCD(778, 987) = 767886 / 767886

GCD(778, 987) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 246

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

LCM(1, 246) = 246

GCD(1, 246) = ( 1 x 246 ) / 246

GCD(1, 246) = 246 / 246

GCD(1, 246) = 1

GCD of 778, 987, 246 is 1
