Given numbers are 207, 249, 311, 620

The list of prime factors of all numbers are

Prime factors of 207 are 3 x 3 x 23

Prime factors of 249 are 3 x 83

Prime factors of 311 are 311

Prime factors of 620 are 2 x 2 x 5 x 31

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

Given numbers are 207, 249, 311, 620

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

Apply this formula for all numbers.

Step1:

LCM(207, 249) = 17181

GCD(207, 249) = ( 207 x 249 ) / 17181

= 207 / 249

= 207

Step2:

LCM(3, 311) = 933

GCD(3, 311) = ( 3 x 311 ) / 933

= 3 / 311

= 3

Step3:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 207, 249, 311, 620 is 1
