Therefore, GCD of numbers 985, 835, 62, 720 is 1

Given Input Data is 985, 835, 62, 720

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

Prime Factorization of 985 is 5 x 197

Prime Factorization of 835 is 5 x 167

Prime Factorization of 62 is 2 x 31

Prime Factorization of 720 is 2 x 2 x 2 x 2 x 3 x 3 x 5

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, 835) = 164495

GCD(985, 835) = ( 985 x 835 ) / 164495

GCD(985, 835) = 822475 / 164495

GCD(985, 835) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 62

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

LCM(5, 62) = 310

GCD(5, 62) = ( 5 x 62 ) / 310

GCD(5, 62) = 310 / 310

GCD(5, 62) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 720

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

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

GCD(1, 720) = 720 / 720

GCD(1, 720) = 1

GCD of 985, 835, 62, 720 is 1
