Given numbers are 668, 255, 424

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

Apply this formula for all numbers.

Step1:

LCM(668, 255) = 170340

GCD(668, 255) = ( 668 x 255 ) / 170340

= 668 / 255

= 668

Step2:

LCM(1, 424) = 424

GCD(1, 424) = ( 1 x 424 ) / 424

= 1 / 424

= 1

So, Greatest Common Divisor of 668, 255, 424 is 1
