Given numbers are 255, 722, 842

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

Apply this formula for all numbers.

Step1:

LCM(255, 722) = 184110

GCD(255, 722) = ( 255 x 722 ) / 184110

= 255 / 722

= 255

Step2:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

So, Greatest Common Divisor of 255, 722, 842 is 1
