Given numbers are 279, 504, 257, 845

The list of prime factors of all numbers are

Prime factors of 279 are 3 x 3 x 31

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

Prime factors of 257 are 257

Prime factors of 845 are 5 x 13 x 13

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

Given numbers are 279, 504, 257, 845

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

Apply this formula for all numbers.

Step1:

LCM(279, 504) = 15624

GCD(279, 504) = ( 279 x 504 ) / 15624

= 279 / 504

= 279

Step2:

LCM(9, 257) = 2313

GCD(9, 257) = ( 9 x 257 ) / 2313

= 9 / 257

= 9

Step3:

LCM(1, 845) = 845

GCD(1, 845) = ( 1 x 845 ) / 845

= 1 / 845

= 1

So, Greatest Common Divisor of 279, 504, 257, 845 is 1
