Given Input Data is 987, 783, 557

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

Prime Factorization of 987 is 3 x 7 x 47

Prime Factorization of 783 is 3 x 3 x 3 x 29

Prime Factorization of 557 is 557

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(987, 783) = 257607

GCD(987, 783) = ( 987 x 783 ) / 257607

GCD(987, 783) = 772821 / 257607

GCD(987, 783) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 557

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

LCM(3, 557) = 1671

GCD(3, 557) = ( 3 x 557 ) / 1671

GCD(3, 557) = 1671 / 1671

GCD(3, 557) = 1

GCD of 987, 783, 557 is 1
