Given numbers are 686, 343, 250, 517

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

Apply this formula for all numbers.

Step1:

LCM(686, 343) = 686

GCD(686, 343) = ( 686 x 343 ) / 686

= 686 / 343

= 686

Step2:

LCM(343, 250) = 85750

GCD(343, 250) = ( 343 x 250 ) / 85750

= 343 / 250

= 343

Step3:

LCM(1, 517) = 517

GCD(1, 517) = ( 1 x 517 ) / 517

= 1 / 517

= 1

So, Greatest Common Divisor of 686, 343, 250, 517 is 1
