Given numbers are 331, 165, 860, 817

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

Apply this formula for all numbers.

Step1:

LCM(331, 165) = 54615

GCD(331, 165) = ( 331 x 165 ) / 54615

= 331 / 165

= 331

Step2:

LCM(1, 860) = 860

GCD(1, 860) = ( 1 x 860 ) / 860

= 1 / 860

= 1

Step3:

LCM(1, 817) = 817

GCD(1, 817) = ( 1 x 817 ) / 817

= 1 / 817

= 1

So, Greatest Common Divisor of 331, 165, 860, 817 is 1
