Therefore, GCD of numbers 796, 290, 78, 621 is 1

Given Input Data is 796, 290, 78, 621

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

Prime Factorization of 796 is 2 x 2 x 199

Prime Factorization of 290 is 2 x 5 x 29

Prime Factorization of 78 is 2 x 3 x 13

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(796, 290) = 115420

GCD(796, 290) = ( 796 x 290 ) / 115420

GCD(796, 290) = 230840 / 115420

GCD(796, 290) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 78

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

LCM(2, 78) = 78

GCD(2, 78) = ( 2 x 78 ) / 78

GCD(2, 78) = 156 / 78

GCD(2, 78) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 621

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

LCM(2, 621) = 1242

GCD(2, 621) = ( 2 x 621 ) / 1242

GCD(2, 621) = 1242 / 1242

GCD(2, 621) = 1

GCD of 796, 290, 78, 621 is 1
