Given Input Data is 658, 880, 271, 861

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

Prime Factorization of 658 is 2 x 7 x 47

Prime Factorization of 880 is 2 x 2 x 2 x 2 x 5 x 11

Prime Factorization of 271 is 271

Prime Factorization of 861 is 3 x 7 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(658, 880) = 289520

GCD(658, 880) = ( 658 x 880 ) / 289520

GCD(658, 880) = 579040 / 289520

GCD(658, 880) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 271

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

LCM(2, 271) = 542

GCD(2, 271) = ( 2 x 271 ) / 542

GCD(2, 271) = 542 / 542

GCD(2, 271) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 861

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

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

GCD(1, 861) = 861 / 861

GCD(1, 861) = 1

GCD of 658, 880, 271, 861 is 1
