Therefore, GCD of numbers 12, 855, 889, 137 is 1

Given Input Data is 12, 855, 889, 137

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

Prime Factorization of 12 is 2 x 2 x 3

Prime Factorization of 855 is 3 x 3 x 5 x 19

Prime Factorization of 889 is 7 x 127

Prime Factorization of 137 is 137

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(12, 855) = 3420

GCD(12, 855) = ( 12 x 855 ) / 3420

GCD(12, 855) = 10260 / 3420

GCD(12, 855) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 889

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

LCM(3, 889) = 2667

GCD(3, 889) = ( 3 x 889 ) / 2667

GCD(3, 889) = 2667 / 2667

GCD(3, 889) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 137

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

LCM(1, 137) = 137

GCD(1, 137) = ( 1 x 137 ) / 137

GCD(1, 137) = 137 / 137

GCD(1, 137) = 1

GCD of 12, 855, 889, 137 is 1
