Given numbers are 817, 889, 788, 866

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

Apply this formula for all numbers.

Step1:

LCM(817, 889) = 726313

GCD(817, 889) = ( 817 x 889 ) / 726313

= 817 / 889

= 817

Step2:

LCM(1, 788) = 788

GCD(1, 788) = ( 1 x 788 ) / 788

= 1 / 788

= 1

Step3:

LCM(1, 866) = 866

GCD(1, 866) = ( 1 x 866 ) / 866

= 1 / 866

= 1

So, Greatest Common Divisor of 817, 889, 788, 866 is 1
