Given numbers are 687, 672, 18, 239

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

Apply this formula for all numbers.

Step1:

LCM(687, 672) = 153888

GCD(687, 672) = ( 687 x 672 ) / 153888

= 687 / 672

= 687

Step2:

LCM(3, 18) = 18

GCD(3, 18) = ( 3 x 18 ) / 18

= 3 / 18

= 3

Step3:

LCM(3, 239) = 717

GCD(3, 239) = ( 3 x 239 ) / 717

= 3 / 239

= 3

So, Greatest Common Divisor of 687, 672, 18, 239 is 1
