Given Input Data is 636, 188, 55, 204

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

Prime Factorization of 636 is 2 x 2 x 3 x 53

Prime Factorization of 188 is 2 x 2 x 47

Prime Factorization of 55 is 5 x 11

Prime Factorization of 204 is 2 x 2 x 3 x 17

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(636, 188) = 29892

GCD(636, 188) = ( 636 x 188 ) / 29892

GCD(636, 188) = 119568 / 29892

GCD(636, 188) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 55

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

LCM(4, 55) = 220

GCD(4, 55) = ( 4 x 55 ) / 220

GCD(4, 55) = 220 / 220

GCD(4, 55) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 204

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

LCM(1, 204) = 204

GCD(1, 204) = ( 1 x 204 ) / 204

GCD(1, 204) = 204 / 204

GCD(1, 204) = 1

GCD of 636, 188, 55, 204 is 1
