Given numbers are 686, 451, 545

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

Apply this formula for all numbers.

Step1:

LCM(686, 451) = 309386

GCD(686, 451) = ( 686 x 451 ) / 309386

= 686 / 451

= 686

Step2:

LCM(1, 545) = 545

GCD(1, 545) = ( 1 x 545 ) / 545

= 1 / 545

= 1

So, Greatest Common Divisor of 686, 451, 545 is 1
