Given numbers are 255, 687, 57, 294

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

Apply this formula for all numbers.

Step1:

LCM(255, 687) = 58395

GCD(255, 687) = ( 255 x 687 ) / 58395

= 255 / 687

= 255

Step2:

LCM(3, 57) = 57

GCD(3, 57) = ( 3 x 57 ) / 57

= 3 / 57

= 3

Step3:

LCM(3, 294) = 294

GCD(3, 294) = ( 3 x 294 ) / 294

= 3 / 294

= 3

So, Greatest Common Divisor of 255, 687, 57, 294 is 3
