Therefore, GCD of numbers 15, 687, 573, 616 is 1

Given Input Data is 15, 687, 573, 616

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

Prime Factorization of 15 is 3 x 5

Prime Factorization of 687 is 3 x 229

Prime Factorization of 573 is 3 x 191

Prime Factorization of 616 is 2 x 2 x 2 x 7 x 11

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, 687) = 3435

GCD(15, 687) = ( 15 x 687 ) / 3435

GCD(15, 687) = 10305 / 3435

GCD(15, 687) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 573

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

LCM(3, 573) = 573

GCD(3, 573) = ( 3 x 573 ) / 573

GCD(3, 573) = 1719 / 573

GCD(3, 573) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 616

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

LCM(3, 616) = 1848

GCD(3, 616) = ( 3 x 616 ) / 1848

GCD(3, 616) = 1848 / 1848

GCD(3, 616) = 1

GCD of 15, 687, 573, 616 is 1
