Given numbers are 686, 294, 399, 494

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

Apply this formula for all numbers.

Step1:

LCM(686, 294) = 2058

GCD(686, 294) = ( 686 x 294 ) / 2058

= 686 / 294

= 686

Step2:

LCM(98, 399) = 5586

GCD(98, 399) = ( 98 x 399 ) / 5586

= 98 / 399

= 98

Step3:

LCM(7, 494) = 3458

GCD(7, 494) = ( 7 x 494 ) / 3458

= 7 / 494

= 7

So, Greatest Common Divisor of 686, 294, 399, 494 is 1
