Therefore, GCD of numbers 51, 756, 441, 457 is 1

Given Input Data is 51, 756, 441, 457

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

Prime Factorization of 51 is 3 x 17

Prime Factorization of 756 is 2 x 2 x 3 x 3 x 3 x 7

Prime Factorization of 441 is 3 x 3 x 7 x 7

Prime Factorization of 457 is 457

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(51, 756) = 12852

GCD(51, 756) = ( 51 x 756 ) / 12852

GCD(51, 756) = 38556 / 12852

GCD(51, 756) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 441

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

LCM(3, 441) = 441

GCD(3, 441) = ( 3 x 441 ) / 441

GCD(3, 441) = 1323 / 441

GCD(3, 441) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 457

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

LCM(3, 457) = 1371

GCD(3, 457) = ( 3 x 457 ) / 1371

GCD(3, 457) = 1371 / 1371

GCD(3, 457) = 1

GCD of 51, 756, 441, 457 is 1
