Given numbers are 686, 478, 485

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

Apply this formula for all numbers.

Step1:

LCM(686, 478) = 163954

GCD(686, 478) = ( 686 x 478 ) / 163954

= 686 / 478

= 686

Step2:

LCM(2, 485) = 970

GCD(2, 485) = ( 2 x 485 ) / 970

= 2 / 485

= 2

So, Greatest Common Divisor of 686, 478, 485 is 1
