Given Input Data is 753, 642, 999, 437

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

Prime Factorization of 753 is 3 x 251

Prime Factorization of 642 is 2 x 3 x 107

Prime Factorization of 999 is 3 x 3 x 3 x 37

Prime Factorization of 437 is 19 x 23

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(753, 642) = 161142

GCD(753, 642) = ( 753 x 642 ) / 161142

GCD(753, 642) = 483426 / 161142

GCD(753, 642) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 999

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

LCM(3, 999) = 999

GCD(3, 999) = ( 3 x 999 ) / 999

GCD(3, 999) = 2997 / 999

GCD(3, 999) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 437

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

LCM(3, 437) = 1311

GCD(3, 437) = ( 3 x 437 ) / 1311

GCD(3, 437) = 1311 / 1311

GCD(3, 437) = 1

GCD of 753, 642, 999, 437 is 1
