Given numbers are 686, 987, 902, 808

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

Apply this formula for all numbers.

Step1:

LCM(686, 987) = 96726

GCD(686, 987) = ( 686 x 987 ) / 96726

= 686 / 987

= 686

Step2:

LCM(7, 902) = 6314

GCD(7, 902) = ( 7 x 902 ) / 6314

= 7 / 902

= 7

Step3:

LCM(1, 808) = 808

GCD(1, 808) = ( 1 x 808 ) / 808

= 1 / 808

= 1

So, Greatest Common Divisor of 686, 987, 902, 808 is 1
