Given Input Data is 782, 621, 795

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

Prime Factorization of 782 is 2 x 17 x 23

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

Prime Factorization of 795 is 3 x 5 x 53

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(782, 621) = 21114

GCD(782, 621) = ( 782 x 621 ) / 21114

GCD(782, 621) = 485622 / 21114

GCD(782, 621) = 23

Step2:

Here we consider the GCD from the above i.e. 23 as first number and the next as 795

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

LCM(23, 795) = 18285

GCD(23, 795) = ( 23 x 795 ) / 18285

GCD(23, 795) = 18285 / 18285

GCD(23, 795) = 1

GCD of 782, 621, 795 is 1
