Therefore, GCD of numbers 985, 689, 510 is 1

Given Input Data is 985, 689, 510

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

Prime Factorization of 985 is 5 x 197

Prime Factorization of 689 is 13 x 53

Prime Factorization of 510 is 2 x 3 x 5 x 17

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, 689) = 678665

GCD(985, 689) = ( 985 x 689 ) / 678665

GCD(985, 689) = 678665 / 678665

GCD(985, 689) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 510

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

LCM(1, 510) = 510

GCD(1, 510) = ( 1 x 510 ) / 510

GCD(1, 510) = 510 / 510

GCD(1, 510) = 1

GCD of 985, 689, 510 is 1
