Given Input Data is 938, 871, 641, 451

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

Prime Factorization of 938 is 2 x 7 x 67

Prime Factorization of 871 is 13 x 67

Prime Factorization of 641 is 641

Prime Factorization of 451 is 11 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(938, 871) = 12194

GCD(938, 871) = ( 938 x 871 ) / 12194

GCD(938, 871) = 816998 / 12194

GCD(938, 871) = 67

Step2:

Here we consider the GCD from the above i.e. 67 as first number and the next as 641

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

LCM(67, 641) = 42947

GCD(67, 641) = ( 67 x 641 ) / 42947

GCD(67, 641) = 42947 / 42947

GCD(67, 641) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 451

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

LCM(1, 451) = 451

GCD(1, 451) = ( 1 x 451 ) / 451

GCD(1, 451) = 451 / 451

GCD(1, 451) = 1

GCD of 938, 871, 641, 451 is 1
