Given Input Data is 372, 772, 84, 221

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

Prime Factorization of 372 is 2 x 2 x 3 x 31

Prime Factorization of 772 is 2 x 2 x 193

Prime Factorization of 84 is 2 x 2 x 3 x 7

Prime Factorization of 221 is 13 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(372, 772) = 71796

GCD(372, 772) = ( 372 x 772 ) / 71796

GCD(372, 772) = 287184 / 71796

GCD(372, 772) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 84

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

LCM(4, 84) = 84

GCD(4, 84) = ( 4 x 84 ) / 84

GCD(4, 84) = 336 / 84

GCD(4, 84) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 221

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

LCM(4, 221) = 884

GCD(4, 221) = ( 4 x 221 ) / 884

GCD(4, 221) = 884 / 884

GCD(4, 221) = 1

GCD of 372, 772, 84, 221 is 1
