Therefore, GCD of numbers 780, 232, 137, 328 is 1

Given Input Data is 780, 232, 137, 328

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

Prime Factorization of 780 is 2 x 2 x 3 x 5 x 13

Prime Factorization of 232 is 2 x 2 x 2 x 29

Prime Factorization of 137 is 137

Prime Factorization of 328 is 2 x 2 x 2 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(780, 232) = 45240

GCD(780, 232) = ( 780 x 232 ) / 45240

GCD(780, 232) = 180960 / 45240

GCD(780, 232) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 137

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

LCM(4, 137) = 548

GCD(4, 137) = ( 4 x 137 ) / 548

GCD(4, 137) = 548 / 548

GCD(4, 137) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 328

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

LCM(1, 328) = 328

GCD(1, 328) = ( 1 x 328 ) / 328

GCD(1, 328) = 328 / 328

GCD(1, 328) = 1

GCD of 780, 232, 137, 328 is 1
