Therefore, GCD of numbers 615, 685, 684 is 1

Given Input Data is 615, 685, 684

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

Prime Factorization of 615 is 3 x 5 x 41

Prime Factorization of 685 is 5 x 137

Prime Factorization of 684 is 2 x 2 x 3 x 3 x 19

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(615, 685) = 84255

GCD(615, 685) = ( 615 x 685 ) / 84255

GCD(615, 685) = 421275 / 84255

GCD(615, 685) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 684

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

LCM(5, 684) = 3420

GCD(5, 684) = ( 5 x 684 ) / 3420

GCD(5, 684) = 3420 / 3420

GCD(5, 684) = 1

GCD of 615, 685, 684 is 1
