Given numbers are 687, 172, 304

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

Apply this formula for all numbers.

Step1:

LCM(687, 172) = 118164

GCD(687, 172) = ( 687 x 172 ) / 118164

= 687 / 172

= 687

Step2:

LCM(1, 304) = 304

GCD(1, 304) = ( 1 x 304 ) / 304

= 1 / 304

= 1

So, Greatest Common Divisor of 687, 172, 304 is 1
