Given Input Data is 651, 623, 838, 749

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

Prime Factorization of 651 is 3 x 7 x 31

Prime Factorization of 623 is 7 x 89

Prime Factorization of 838 is 2 x 419

Prime Factorization of 749 is 7 x 107

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(651, 623) = 57939

GCD(651, 623) = ( 651 x 623 ) / 57939

GCD(651, 623) = 405573 / 57939

GCD(651, 623) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 838

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

LCM(7, 838) = 5866

GCD(7, 838) = ( 7 x 838 ) / 5866

GCD(7, 838) = 5866 / 5866

GCD(7, 838) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 749

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

LCM(1, 749) = 749

GCD(1, 749) = ( 1 x 749 ) / 749

GCD(1, 749) = 749 / 749

GCD(1, 749) = 1

GCD of 651, 623, 838, 749 is 1
