Given numbers are 686, 248, 763, 678

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

Apply this formula for all numbers.

Step1:

LCM(686, 248) = 85064

GCD(686, 248) = ( 686 x 248 ) / 85064

= 686 / 248

= 686

Step2:

LCM(2, 763) = 1526

GCD(2, 763) = ( 2 x 763 ) / 1526

= 2 / 763

= 2

Step3:

LCM(1, 678) = 678

GCD(1, 678) = ( 1 x 678 ) / 678

= 1 / 678

= 1

So, Greatest Common Divisor of 686, 248, 763, 678 is 1
