Given numbers are 136, 256, 687

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

Apply this formula for all numbers.

Step1:

LCM(136, 256) = 4352

GCD(136, 256) = ( 136 x 256 ) / 4352

= 136 / 256

= 136

Step2:

LCM(8, 687) = 5496

GCD(8, 687) = ( 8 x 687 ) / 5496

= 8 / 687

= 8

So, Greatest Common Divisor of 136, 256, 687 is 1
