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

Apply this formula for all numbers.

Step1:

LCM(255, 393) = 33405

GCD(255, 393) = ( 255 x 393 ) / 33405

= 255 / 393

= 255

Step2:

LCM(3, 885) = 885

GCD(3, 885) = ( 3 x 885 ) / 885

= 3 / 885

= 3

Step3:

LCM(3, 615) = 615

GCD(3, 615) = ( 3 x 615 ) / 615

= 3 / 615

= 3

So, Greatest Common Divisor of 255, 393, 885, 615 is 3
