Given numbers are 255, 556, 291

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

Apply this formula for all numbers.

Step1:

LCM(255, 556) = 141780

GCD(255, 556) = ( 255 x 556 ) / 141780

= 255 / 556

= 255

Step2:

LCM(1, 291) = 291

GCD(1, 291) = ( 1 x 291 ) / 291

= 1 / 291

= 1

So, Greatest Common Divisor of 255, 556, 291 is 1
