Given numbers are 686, 389, 470, 299

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

Apply this formula for all numbers.

Step1:

LCM(686, 389) = 266854

GCD(686, 389) = ( 686 x 389 ) / 266854

= 686 / 389

= 686

Step2:

LCM(1, 470) = 470

GCD(1, 470) = ( 1 x 470 ) / 470

= 1 / 470

= 1

Step3:

LCM(1, 299) = 299

GCD(1, 299) = ( 1 x 299 ) / 299

= 1 / 299

= 1

So, Greatest Common Divisor of 686, 389, 470, 299 is 1
