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, 39) = 39

GCD(3, 39) = ( 3 x 39 ) / 39

= 3 / 39

= 3

Step3:

LCM(3, 753) = 753

GCD(3, 753) = ( 3 x 753 ) / 753

= 3 / 753

= 3

So, Greatest Common Divisor of 255, 687, 39, 753 is 3
