Given numbers are 817, 563, 66

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

Apply this formula for all numbers.

Step1:

LCM(817, 563) = 459971

GCD(817, 563) = ( 817 x 563 ) / 459971

= 817 / 563

= 817

Step2:

LCM(1, 66) = 66

GCD(1, 66) = ( 1 x 66 ) / 66

= 1 / 66

= 1

So, Greatest Common Divisor of 817, 563, 66 is 1
