Given Input Data is 155, 635, 22, 203

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

Prime Factorization of 155 is 5 x 31

Prime Factorization of 635 is 5 x 127

Prime Factorization of 22 is 2 x 11

Prime Factorization of 203 is 7 x 29

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(155, 635) = 19685

GCD(155, 635) = ( 155 x 635 ) / 19685

GCD(155, 635) = 98425 / 19685

GCD(155, 635) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 22

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

LCM(5, 22) = 110

GCD(5, 22) = ( 5 x 22 ) / 110

GCD(5, 22) = 110 / 110

GCD(5, 22) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 203

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

LCM(1, 203) = 203

GCD(1, 203) = ( 1 x 203 ) / 203

GCD(1, 203) = 203 / 203

GCD(1, 203) = 1

GCD of 155, 635, 22, 203 is 1
