Given numbers are 656, 687, 206

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

Apply this formula for all numbers.

Step1:

LCM(656, 687) = 450672

GCD(656, 687) = ( 656 x 687 ) / 450672

= 656 / 687

= 656

Step2:

LCM(1, 206) = 206

GCD(1, 206) = ( 1 x 206 ) / 206

= 1 / 206

= 1

So, Greatest Common Divisor of 656, 687, 206 is 1
