Given numbers are 207, 489, 464, 391

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

Apply this formula for all numbers.

Step1:

LCM(207, 489) = 33741

GCD(207, 489) = ( 207 x 489 ) / 33741

= 207 / 489

= 207

Step2:

LCM(3, 464) = 1392

GCD(3, 464) = ( 3 x 464 ) / 1392

= 3 / 464

= 3

Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 207, 489, 464, 391 is 1
