Given numbers are 689, 393, 234

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

Apply this formula for all numbers.

Step1:

LCM(689, 393) = 270777

GCD(689, 393) = ( 689 x 393 ) / 270777

= 689 / 393

= 689

Step2:

LCM(1, 234) = 234

GCD(1, 234) = ( 1 x 234 ) / 234

= 1 / 234

= 1

So, Greatest Common Divisor of 689, 393, 234 is 1
