Therefore, GCD of numbers 639, 555, 601, 118 is 1

Given Input Data is 639, 555, 601, 118

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

Prime Factorization of 639 is 3 x 3 x 71

Prime Factorization of 555 is 3 x 5 x 37

Prime Factorization of 601 is 601

Prime Factorization of 118 is 2 x 59

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(639, 555) = 118215

GCD(639, 555) = ( 639 x 555 ) / 118215

GCD(639, 555) = 354645 / 118215

GCD(639, 555) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 601

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

LCM(3, 601) = 1803

GCD(3, 601) = ( 3 x 601 ) / 1803

GCD(3, 601) = 1803 / 1803

GCD(3, 601) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 118

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

LCM(1, 118) = 118

GCD(1, 118) = ( 1 x 118 ) / 118

GCD(1, 118) = 118 / 118

GCD(1, 118) = 1

GCD of 639, 555, 601, 118 is 1
