So the Greatest Common Divisior 915, 626, 621, 859 is 1.

Therefore, GCD of numbers 915, 626, 621, 859 is 1

Given Input Data is 915, 626, 621, 859

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

Prime Factorization of 915 is 3 x 5 x 61

Prime Factorization of 626 is 2 x 313

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

Prime Factorization of 859 is 859

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(915, 626) = 572790

GCD(915, 626) = ( 915 x 626 ) / 572790

GCD(915, 626) = 572790 / 572790

GCD(915, 626) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 621

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

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

GCD(1, 621) = 621 / 621

GCD(1, 621) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 859

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

LCM(1, 859) = 859

GCD(1, 859) = ( 1 x 859 ) / 859

GCD(1, 859) = 859 / 859

GCD(1, 859) = 1

GCD of 915, 626, 621, 859 is 1
