Given numbers are 687, 344, 905, 886

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

Apply this formula for all numbers.

Step1:

LCM(687, 344) = 236328

GCD(687, 344) = ( 687 x 344 ) / 236328

= 687 / 344

= 687

Step2:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

Step3:

LCM(1, 886) = 886

GCD(1, 886) = ( 1 x 886 ) / 886

= 1 / 886

= 1

So, Greatest Common Divisor of 687, 344, 905, 886 is 1
