Therefore, GCD of numbers 635, 774, 815 is 1

Given Input Data is 635, 774, 815

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

Prime Factorization of 635 is 5 x 127

Prime Factorization of 774 is 2 x 3 x 3 x 43

Prime Factorization of 815 is 5 x 163

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(635, 774) = 491490

GCD(635, 774) = ( 635 x 774 ) / 491490

GCD(635, 774) = 491490 / 491490

GCD(635, 774) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 815

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

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

GCD(1, 815) = 815 / 815

GCD(1, 815) = 1

GCD of 635, 774, 815 is 1
