Given Input Data is 452, 620, 180, 187

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

Prime Factorization of 452 is 2 x 2 x 113

Prime Factorization of 620 is 2 x 2 x 5 x 31

Prime Factorization of 180 is 2 x 2 x 3 x 3 x 5

Prime Factorization of 187 is 11 x 17

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(452, 620) = 70060

GCD(452, 620) = ( 452 x 620 ) / 70060

GCD(452, 620) = 280240 / 70060

GCD(452, 620) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 180

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

LCM(4, 180) = 180

GCD(4, 180) = ( 4 x 180 ) / 180

GCD(4, 180) = 720 / 180

GCD(4, 180) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 187

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

LCM(4, 187) = 748

GCD(4, 187) = ( 4 x 187 ) / 748

GCD(4, 187) = 748 / 748

GCD(4, 187) = 1

GCD of 452, 620, 180, 187 is 1
