Given numbers are 817, 123, 665

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

Apply this formula for all numbers.

Step1:

LCM(817, 123) = 100491

GCD(817, 123) = ( 817 x 123 ) / 100491

= 817 / 123

= 817

Step2:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 817, 123, 665 is 1
