Given numbers are 428, 296, 255

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

Apply this formula for all numbers.

Step1:

LCM(428, 296) = 31672

GCD(428, 296) = ( 428 x 296 ) / 31672

= 428 / 296

= 428

Step2:

LCM(4, 255) = 1020

GCD(4, 255) = ( 4 x 255 ) / 1020

= 4 / 255

= 4

So, Greatest Common Divisor of 428, 296, 255 is 1
