Given numbers are 322, 205, 689

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

Apply this formula for all numbers.

Step1:

LCM(322, 205) = 66010

GCD(322, 205) = ( 322 x 205 ) / 66010

= 322 / 205

= 322

Step2:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

So, Greatest Common Divisor of 322, 205, 689 is 1
