Given numbers are 406, 965, 687

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

Apply this formula for all numbers.

Step1:

LCM(406, 965) = 391790

GCD(406, 965) = ( 406 x 965 ) / 391790

= 406 / 965

= 406

Step2:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 406, 965, 687 is 1
