Therefore, GCD of numbers 621, 609, 33, 308 is 1

Given Input Data is 621, 609, 33, 308

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

Prime Factorization of 621 is 3 x 3 x 3 x 23

Prime Factorization of 609 is 3 x 7 x 29

Prime Factorization of 33 is 3 x 11

Prime Factorization of 308 is 2 x 2 x 7 x 11

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(621, 609) = 126063

GCD(621, 609) = ( 621 x 609 ) / 126063

GCD(621, 609) = 378189 / 126063

GCD(621, 609) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 33

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

LCM(3, 33) = 33

GCD(3, 33) = ( 3 x 33 ) / 33

GCD(3, 33) = 99 / 33

GCD(3, 33) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 308

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

LCM(3, 308) = 924

GCD(3, 308) = ( 3 x 308 ) / 924

GCD(3, 308) = 924 / 924

GCD(3, 308) = 1

GCD of 621, 609, 33, 308 is 1
