Therefore, GCD of numbers 462, 979, 57, 661 is 1

Given Input Data is 462, 979, 57, 661

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

Prime Factorization of 462 is 2 x 3 x 7 x 11

Prime Factorization of 979 is 11 x 89

Prime Factorization of 57 is 3 x 19

Prime Factorization of 661 is 661

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(462, 979) = 41118

GCD(462, 979) = ( 462 x 979 ) / 41118

GCD(462, 979) = 452298 / 41118

GCD(462, 979) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 57

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

LCM(11, 57) = 627

GCD(11, 57) = ( 11 x 57 ) / 627

GCD(11, 57) = 627 / 627

GCD(11, 57) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 661

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

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

GCD(1, 661) = 661 / 661

GCD(1, 661) = 1

GCD of 462, 979, 57, 661 is 1
