Given Input Data is 634, 985, 885, 828

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

Prime Factorization of 634 is 2 x 317

Prime Factorization of 985 is 5 x 197

Prime Factorization of 885 is 3 x 5 x 59

Prime Factorization of 828 is 2 x 2 x 3 x 3 x 23

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(634, 985) = 624490

GCD(634, 985) = ( 634 x 985 ) / 624490

GCD(634, 985) = 624490 / 624490

GCD(634, 985) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 885

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

LCM(1, 885) = 885

GCD(1, 885) = ( 1 x 885 ) / 885

GCD(1, 885) = 885 / 885

GCD(1, 885) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 828

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

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

GCD(1, 828) = 828 / 828

GCD(1, 828) = 1

GCD of 634, 985, 885, 828 is 1
