Given numbers are 424, 813, 689

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

Apply this formula for all numbers.

Step1:

LCM(424, 813) = 344712

GCD(424, 813) = ( 424 x 813 ) / 344712

= 424 / 813

= 424

Step2:

LCM(1, 689) = 689

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

= 1 / 689

= 1

So, Greatest Common Divisor of 424, 813, 689 is 1
