Given numbers are 518, 644, 203, 444

The list of prime factors of all numbers are

Prime factors of 518 are 2 x 7 x 37

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 203 are 7 x 29

Prime factors of 444 are 2 x 2 x 3 x 37

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 518, 644, 203, 444

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(518, 644) = 23828

GCD(518, 644) = ( 518 x 644 ) / 23828

= 518 / 644

= 518

Step2:

LCM(14, 203) = 406

GCD(14, 203) = ( 14 x 203 ) / 406

= 14 / 203

= 14

Step3:

LCM(7, 444) = 3108

GCD(7, 444) = ( 7 x 444 ) / 3108

= 7 / 444

= 7

So, Greatest Common Divisor of 518, 644, 203, 444 is 1
