Given numbers are 298, 689, 306

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

Apply this formula for all numbers.

Step1:

LCM(298, 689) = 205322

GCD(298, 689) = ( 298 x 689 ) / 205322

= 298 / 689

= 298

Step2:

LCM(1, 306) = 306

GCD(1, 306) = ( 1 x 306 ) / 306

= 1 / 306

= 1

So, Greatest Common Divisor of 298, 689, 306 is 1
