Given Input Data is 441, 216, 634, 155

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

Prime Factorization of 441 is 3 x 3 x 7 x 7

Prime Factorization of 216 is 2 x 2 x 2 x 3 x 3 x 3

Prime Factorization of 634 is 2 x 317

Prime Factorization of 155 is 5 x 31

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(441, 216) = 10584

GCD(441, 216) = ( 441 x 216 ) / 10584

GCD(441, 216) = 95256 / 10584

GCD(441, 216) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 634

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

LCM(9, 634) = 5706

GCD(9, 634) = ( 9 x 634 ) / 5706

GCD(9, 634) = 5706 / 5706

GCD(9, 634) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 155

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

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

GCD(1, 155) = 155 / 155

GCD(1, 155) = 1

GCD of 441, 216, 634, 155 is 1
