Given numbers are 687, 891, 118

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

Apply this formula for all numbers.

Step1:

LCM(687, 891) = 204039

GCD(687, 891) = ( 687 x 891 ) / 204039

= 687 / 891

= 687

Step2:

LCM(3, 118) = 354

GCD(3, 118) = ( 3 x 118 ) / 354

= 3 / 118

= 3

So, Greatest Common Divisor of 687, 891, 118 is 1
