Given numbers are 286, 218, 689, 418

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

Apply this formula for all numbers.

Step1:

LCM(286, 218) = 31174

GCD(286, 218) = ( 286 x 218 ) / 31174

= 286 / 218

= 286

Step2:

LCM(2, 689) = 1378

GCD(2, 689) = ( 2 x 689 ) / 1378

= 2 / 689

= 2

Step3:

LCM(1, 418) = 418

GCD(1, 418) = ( 1 x 418 ) / 418

= 1 / 418

= 1

So, Greatest Common Divisor of 286, 218, 689, 418 is 1
