Therefore, GCD of numbers 21, 552, 472, 377 is 1

Given Input Data is 21, 552, 472, 377

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

Prime Factorization of 21 is 3 x 7

Prime Factorization of 552 is 2 x 2 x 2 x 3 x 23

Prime Factorization of 472 is 2 x 2 x 2 x 59

Prime Factorization of 377 is 13 x 29

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(21, 552) = 3864

GCD(21, 552) = ( 21 x 552 ) / 3864

GCD(21, 552) = 11592 / 3864

GCD(21, 552) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 472

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

LCM(3, 472) = 1416

GCD(3, 472) = ( 3 x 472 ) / 1416

GCD(3, 472) = 1416 / 1416

GCD(3, 472) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 377

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

LCM(1, 377) = 377

GCD(1, 377) = ( 1 x 377 ) / 377

GCD(1, 377) = 377 / 377

GCD(1, 377) = 1

GCD of 21, 552, 472, 377 is 1
