Given Input Data is 15, 576, 551, 685

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

Prime Factorization of 15 is 3 x 5

Prime Factorization of 576 is 2 x 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime Factorization of 551 is 19 x 29

Prime Factorization of 685 is 5 x 137

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(15, 576) = 2880

GCD(15, 576) = ( 15 x 576 ) / 2880

GCD(15, 576) = 8640 / 2880

GCD(15, 576) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 551

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

LCM(3, 551) = 1653

GCD(3, 551) = ( 3 x 551 ) / 1653

GCD(3, 551) = 1653 / 1653

GCD(3, 551) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 685

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

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

GCD(1, 685) = 685 / 685

GCD(1, 685) = 1

GCD of 15, 576, 551, 685 is 1
