Given Input Data is 435, 312, 845, 959

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

Prime Factorization of 435 is 3 x 5 x 29

Prime Factorization of 312 is 2 x 2 x 2 x 3 x 13

Prime Factorization of 845 is 5 x 13 x 13

Prime Factorization of 959 is 7 x 137

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(435, 312) = 45240

GCD(435, 312) = ( 435 x 312 ) / 45240

GCD(435, 312) = 135720 / 45240

GCD(435, 312) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 845

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

LCM(3, 845) = 2535

GCD(3, 845) = ( 3 x 845 ) / 2535

GCD(3, 845) = 2535 / 2535

GCD(3, 845) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 959

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

LCM(1, 959) = 959

GCD(1, 959) = ( 1 x 959 ) / 959

GCD(1, 959) = 959 / 959

GCD(1, 959) = 1

GCD of 435, 312, 845, 959 is 1
