The list of prime factors of all numbers are

Prime factors of 249 are 3 x 83

Prime factors of 939 are 3 x 313

Prime factors of 455 are 5 x 7 x 13

Prime factors of 864 are 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

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

Given numbers are 249, 939, 455, 864

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

Apply this formula for all numbers.

Step1:

LCM(249, 939) = 77937

GCD(249, 939) = ( 249 x 939 ) / 77937

= 249 / 939

= 249

Step2:

LCM(3, 455) = 1365

GCD(3, 455) = ( 3 x 455 ) / 1365

= 3 / 455

= 3

Step3:

LCM(1, 864) = 864

GCD(1, 864) = ( 1 x 864 ) / 864

= 1 / 864

= 1

So, Greatest Common Divisor of 249, 939, 455, 864 is 1
