Given Input Data is 985, 870, 851, 758

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

Prime Factorization of 985 is 5 x 197

Prime Factorization of 870 is 2 x 3 x 5 x 29

Prime Factorization of 851 is 23 x 37

Prime Factorization of 758 is 2 x 379

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(985, 870) = 171390

GCD(985, 870) = ( 985 x 870 ) / 171390

GCD(985, 870) = 856950 / 171390

GCD(985, 870) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 851

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

LCM(5, 851) = 4255

GCD(5, 851) = ( 5 x 851 ) / 4255

GCD(5, 851) = 4255 / 4255

GCD(5, 851) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 758

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

LCM(1, 758) = 758

GCD(1, 758) = ( 1 x 758 ) / 758

GCD(1, 758) = 758 / 758

GCD(1, 758) = 1

GCD of 985, 870, 851, 758 is 1
