Given numbers are 544, 638, 205, 309

The list of prime factors of all numbers are

Prime factors of 544 are 2 x 2 x 2 x 2 x 2 x 17

Prime factors of 638 are 2 x 11 x 29

Prime factors of 205 are 5 x 41

Prime factors of 309 are 3 x 103

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

Given numbers are 544, 638, 205, 309

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

Apply this formula for all numbers.

Step1:

LCM(544, 638) = 173536

GCD(544, 638) = ( 544 x 638 ) / 173536

= 544 / 638

= 544

Step2:

LCM(2, 205) = 410

GCD(2, 205) = ( 2 x 205 ) / 410

= 2 / 205

= 2

Step3:

LCM(1, 309) = 309

GCD(1, 309) = ( 1 x 309 ) / 309

= 1 / 309

= 1

So, Greatest Common Divisor of 544, 638, 205, 309 is 1
