Given numbers are 686, 698, 386, 244

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

Apply this formula for all numbers.

Step1:

LCM(686, 698) = 239414

GCD(686, 698) = ( 686 x 698 ) / 239414

= 686 / 698

= 686

Step2:

LCM(2, 386) = 386

GCD(2, 386) = ( 2 x 386 ) / 386

= 2 / 386

= 2

Step3:

LCM(2, 244) = 244

GCD(2, 244) = ( 2 x 244 ) / 244

= 2 / 244

= 2

So, Greatest Common Divisor of 686, 698, 386, 244 is 2
