Given Input Data is 276, 138, 979, 461

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

Prime Factorization of 276 is 2 x 2 x 3 x 23

Prime Factorization of 138 is 2 x 3 x 23

Prime Factorization of 979 is 11 x 89

Prime Factorization of 461 is 461

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(276, 138) = 276

GCD(276, 138) = ( 276 x 138 ) / 276

GCD(276, 138) = 38088 / 276

GCD(276, 138) = 138

Step2:

Here we consider the GCD from the above i.e. 138 as first number and the next as 979

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

LCM(138, 979) = 135102

GCD(138, 979) = ( 138 x 979 ) / 135102

GCD(138, 979) = 135102 / 135102

GCD(138, 979) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 461

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

LCM(1, 461) = 461

GCD(1, 461) = ( 1 x 461 ) / 461

GCD(1, 461) = 461 / 461

GCD(1, 461) = 1

GCD of 276, 138, 979, 461 is 1
