Given Input Data is 129, 885, 815, 760

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

Prime Factorization of 129 is 3 x 43

Prime Factorization of 885 is 3 x 5 x 59

Prime Factorization of 815 is 5 x 163

Prime Factorization of 760 is 2 x 2 x 2 x 5 x 19

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(129, 885) = 38055

GCD(129, 885) = ( 129 x 885 ) / 38055

GCD(129, 885) = 114165 / 38055

GCD(129, 885) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 815

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

LCM(3, 815) = 2445

GCD(3, 815) = ( 3 x 815 ) / 2445

GCD(3, 815) = 2445 / 2445

GCD(3, 815) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 760

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

LCM(1, 760) = 760

GCD(1, 760) = ( 1 x 760 ) / 760

GCD(1, 760) = 760 / 760

GCD(1, 760) = 1

GCD of 129, 885, 815, 760 is 1
