Therefore, GCD of numbers 239, 688, 889, 778 is 1

Given Input Data is 239, 688, 889, 778

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

Prime Factorization of 239 is 239

Prime Factorization of 688 is 2 x 2 x 2 x 2 x 43

Prime Factorization of 889 is 7 x 127

Prime Factorization of 778 is 2 x 389

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(239, 688) = 164432

GCD(239, 688) = ( 239 x 688 ) / 164432

GCD(239, 688) = 164432 / 164432

GCD(239, 688) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 889

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

LCM(1, 889) = 889

GCD(1, 889) = ( 1 x 889 ) / 889

GCD(1, 889) = 889 / 889

GCD(1, 889) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 778

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

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

GCD(1, 778) = 778 / 778

GCD(1, 778) = 1

GCD of 239, 688, 889, 778 is 1
