Given numbers are 817, 822, 255

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

Apply this formula for all numbers.

Step1:

LCM(817, 822) = 671574

GCD(817, 822) = ( 817 x 822 ) / 671574

= 817 / 822

= 817

Step2:

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

= 1 / 255

= 1

So, Greatest Common Divisor of 817, 822, 255 is 1
