Therefore, GCD of numbers 658, 651, 81, 371 is 1

Given Input Data is 658, 651, 81, 371

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 651 is 3 x 7 x 31

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 371 is 7 x 53

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, 651) = 61194

GCD(658, 651) = ( 658 x 651 ) / 61194

GCD(658, 651) = 428358 / 61194

GCD(658, 651) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 81

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

LCM(7, 81) = 567

GCD(7, 81) = ( 7 x 81 ) / 567

GCD(7, 81) = 567 / 567

GCD(7, 81) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 371

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

LCM(1, 371) = 371

GCD(1, 371) = ( 1 x 371 ) / 371

GCD(1, 371) = 371 / 371

GCD(1, 371) = 1

GCD of 658, 651, 81, 371 is 1
