Given Input Data is 172, 516, 869, 286

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

Prime Factorization of 172 is 2 x 2 x 43

Prime Factorization of 516 is 2 x 2 x 3 x 43

Prime Factorization of 869 is 11 x 79

Prime Factorization of 286 is 2 x 11 x 13

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(172, 516) = 516

GCD(172, 516) = ( 172 x 516 ) / 516

GCD(172, 516) = 88752 / 516

GCD(172, 516) = 172

Step2:

Here we consider the GCD from the above i.e. 172 as first number and the next as 869

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

LCM(172, 869) = 149468

GCD(172, 869) = ( 172 x 869 ) / 149468

GCD(172, 869) = 149468 / 149468

GCD(172, 869) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 286

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

LCM(1, 286) = 286

GCD(1, 286) = ( 1 x 286 ) / 286

GCD(1, 286) = 286 / 286

GCD(1, 286) = 1

GCD of 172, 516, 869, 286 is 1
