Given numbers are 255, 398, 722

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

Apply this formula for all numbers.

Step1:

LCM(255, 398) = 101490

GCD(255, 398) = ( 255 x 398 ) / 101490

= 255 / 398

= 255

Step2:

LCM(1, 722) = 722

GCD(1, 722) = ( 1 x 722 ) / 722

= 1 / 722

= 1

So, Greatest Common Divisor of 255, 398, 722 is 1
