Therefore, GCD of numbers 987, 948, 97, 779 is 1

Given Input Data is 987, 948, 97, 779

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 948 is 2 x 2 x 3 x 79

Prime Factorization of 97 is 97

Prime Factorization of 779 is 19 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(987, 948) = 311892

GCD(987, 948) = ( 987 x 948 ) / 311892

GCD(987, 948) = 935676 / 311892

GCD(987, 948) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 97

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

LCM(3, 97) = 291

GCD(3, 97) = ( 3 x 97 ) / 291

GCD(3, 97) = 291 / 291

GCD(3, 97) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 779

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

LCM(1, 779) = 779

GCD(1, 779) = ( 1 x 779 ) / 779

GCD(1, 779) = 779 / 779

GCD(1, 779) = 1

GCD of 987, 948, 97, 779 is 1
