Therefore, GCD of numbers 274, 255, 57 is 1

Given Input Data is 274, 255, 57

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

Prime Factorization of 274 is 2 x 137

Prime Factorization of 255 is 3 x 5 x 17

Prime Factorization of 57 is 3 x 19

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(274, 255) = 69870

GCD(274, 255) = ( 274 x 255 ) / 69870

GCD(274, 255) = 69870 / 69870

GCD(274, 255) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 57

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

LCM(1, 57) = 57

GCD(1, 57) = ( 1 x 57 ) / 57

GCD(1, 57) = 57 / 57

GCD(1, 57) = 1

GCD of 274, 255, 57 is 1
