Therefore, GCD of numbers 792, 156, 47, 405 is 1

Given Input Data is 792, 156, 47, 405

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

Prime Factorization of 792 is 2 x 2 x 2 x 3 x 3 x 11

Prime Factorization of 156 is 2 x 2 x 3 x 13

Prime Factorization of 47 is 47

Prime Factorization of 405 is 3 x 3 x 3 x 3 x 5

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(792, 156) = 10296

GCD(792, 156) = ( 792 x 156 ) / 10296

GCD(792, 156) = 123552 / 10296

GCD(792, 156) = 12

Step2:

Here we consider the GCD from the above i.e. 12 as first number and the next as 47

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

LCM(12, 47) = 564

GCD(12, 47) = ( 12 x 47 ) / 564

GCD(12, 47) = 564 / 564

GCD(12, 47) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 405

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

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

GCD(1, 405) = 405 / 405

GCD(1, 405) = 1

GCD of 792, 156, 47, 405 is 1
