Given numbers are 686, 778, 413

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

Apply this formula for all numbers.

Step1:

LCM(686, 778) = 266854

GCD(686, 778) = ( 686 x 778 ) / 266854

= 686 / 778

= 686

Step2:

LCM(2, 413) = 826

GCD(2, 413) = ( 2 x 413 ) / 826

= 2 / 413

= 2

So, Greatest Common Divisor of 686, 778, 413 is 1
