Given numbers are 686, 909, 218, 372

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

Apply this formula for all numbers.

Step1:

LCM(686, 909) = 623574

GCD(686, 909) = ( 686 x 909 ) / 623574

= 686 / 909

= 686

Step2:

LCM(1, 218) = 218

GCD(1, 218) = ( 1 x 218 ) / 218

= 1 / 218

= 1

Step3:

LCM(1, 372) = 372

GCD(1, 372) = ( 1 x 372 ) / 372

= 1 / 372

= 1

So, Greatest Common Divisor of 686, 909, 218, 372 is 1
