Given Input Data is 624, 159, 725, 747

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

Prime Factorization of 624 is 2 x 2 x 2 x 2 x 3 x 13

Prime Factorization of 159 is 3 x 53

Prime Factorization of 725 is 5 x 5 x 29

Prime Factorization of 747 is 3 x 3 x 83

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(624, 159) = 33072

GCD(624, 159) = ( 624 x 159 ) / 33072

GCD(624, 159) = 99216 / 33072

GCD(624, 159) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 725

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

LCM(3, 725) = 2175

GCD(3, 725) = ( 3 x 725 ) / 2175

GCD(3, 725) = 2175 / 2175

GCD(3, 725) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 747

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

LCM(1, 747) = 747

GCD(1, 747) = ( 1 x 747 ) / 747

GCD(1, 747) = 747 / 747

GCD(1, 747) = 1

GCD of 624, 159, 725, 747 is 1
