Therefore, GCD of numbers 380, 616, 628, 621 is 1

Given Input Data is 380, 616, 628, 621

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

Prime Factorization of 380 is 2 x 2 x 5 x 19

Prime Factorization of 616 is 2 x 2 x 2 x 7 x 11

Prime Factorization of 628 is 2 x 2 x 157

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

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(380, 616) = 58520

GCD(380, 616) = ( 380 x 616 ) / 58520

GCD(380, 616) = 234080 / 58520

GCD(380, 616) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 628

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

LCM(4, 628) = 628

GCD(4, 628) = ( 4 x 628 ) / 628

GCD(4, 628) = 2512 / 628

GCD(4, 628) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 621

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

LCM(4, 621) = 2484

GCD(4, 621) = ( 4 x 621 ) / 2484

GCD(4, 621) = 2484 / 2484

GCD(4, 621) = 1

GCD of 380, 616, 628, 621 is 1
