Given Input Data is 687, 777, 532, 555

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

Prime Factorization of 687 is 3 x 229

Prime Factorization of 777 is 3 x 7 x 37

Prime Factorization of 532 is 2 x 2 x 7 x 19

Prime Factorization of 555 is 3 x 5 x 37

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(687, 777) = 177933

GCD(687, 777) = ( 687 x 777 ) / 177933

GCD(687, 777) = 533799 / 177933

GCD(687, 777) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 532

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

LCM(3, 532) = 1596

GCD(3, 532) = ( 3 x 532 ) / 1596

GCD(3, 532) = 1596 / 1596

GCD(3, 532) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 555

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

LCM(1, 555) = 555

GCD(1, 555) = ( 1 x 555 ) / 555

GCD(1, 555) = 555 / 555

GCD(1, 555) = 1

GCD of 687, 777, 532, 555 is 1
