Given numbers are 686, 104, 518, 479
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 104) = 35672
GCD(686, 104) = ( 686 x 104 ) / 35672
= 686 / 104
= 686
Step2:
LCM(2, 518) = 518
GCD(2, 518) = ( 2 x 518 ) / 518
= 2 / 518
= 2
Step3:
LCM(2, 479) = 958
GCD(2, 479) = ( 2 x 479 ) / 958
= 2 / 479
= 2
So, Greatest Common Divisor of 686, 104, 518, 479 is 1
