Given numbers are 684, 721, 223, 817

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

Apply this formula for all numbers.

Step1:

LCM(684, 721) = 493164

GCD(684, 721) = ( 684 x 721 ) / 493164

= 684 / 721

= 684

Step2:

LCM(1, 223) = 223

GCD(1, 223) = ( 1 x 223 ) / 223

= 1 / 223

= 1

Step3:

LCM(1, 817) = 817

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

= 1 / 817

= 1

So, Greatest Common Divisor of 684, 721, 223, 817 is 1
