Therefore, GCD of numbers 21, 615, 794, 732 is 1

Given Input Data is 21, 615, 794, 732

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

Prime Factorization of 21 is 3 x 7

Prime Factorization of 615 is 3 x 5 x 41

Prime Factorization of 794 is 2 x 397

Prime Factorization of 732 is 2 x 2 x 3 x 61

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, 615) = 4305

GCD(21, 615) = ( 21 x 615 ) / 4305

GCD(21, 615) = 12915 / 4305

GCD(21, 615) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 794

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

LCM(3, 794) = 2382

GCD(3, 794) = ( 3 x 794 ) / 2382

GCD(3, 794) = 2382 / 2382

GCD(3, 794) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 732

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

LCM(1, 732) = 732

GCD(1, 732) = ( 1 x 732 ) / 732

GCD(1, 732) = 732 / 732

GCD(1, 732) = 1

GCD of 21, 615, 794, 732 is 1
