Given Input Data is 644, 236, 361, 519

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

Prime Factorization of 644 is 2 x 2 x 7 x 23

Prime Factorization of 236 is 2 x 2 x 59

Prime Factorization of 361 is 19 x 19

Prime Factorization of 519 is 3 x 173

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(644, 236) = 37996

GCD(644, 236) = ( 644 x 236 ) / 37996

GCD(644, 236) = 151984 / 37996

GCD(644, 236) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 361

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

LCM(4, 361) = 1444

GCD(4, 361) = ( 4 x 361 ) / 1444

GCD(4, 361) = 1444 / 1444

GCD(4, 361) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 519

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

LCM(1, 519) = 519

GCD(1, 519) = ( 1 x 519 ) / 519

GCD(1, 519) = 519 / 519

GCD(1, 519) = 1

GCD of 644, 236, 361, 519 is 1
