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

Apply this formula for all numbers.

Step1:

LCM(279, 217) = 1953

GCD(279, 217) = ( 279 x 217 ) / 1953

= 279 / 217

= 279

Step2:

LCM(31, 869) = 26939

GCD(31, 869) = ( 31 x 869 ) / 26939

= 31 / 869

= 31

So, Greatest Common Divisor of 279, 217, 869 is 1
