Given numbers are 686, 307, 545, 662

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

Apply this formula for all numbers.

Step1:

LCM(686, 307) = 210602

GCD(686, 307) = ( 686 x 307 ) / 210602

= 686 / 307

= 686

Step2:

LCM(1, 545) = 545

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

= 1 / 545

= 1

Step3:

LCM(1, 662) = 662

GCD(1, 662) = ( 1 x 662 ) / 662

= 1 / 662

= 1

So, Greatest Common Divisor of 686, 307, 545, 662 is 1
