Given numbers are 687, 981, 322, 413

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

Apply this formula for all numbers.

Step1:

LCM(687, 981) = 224649

GCD(687, 981) = ( 687 x 981 ) / 224649

= 687 / 981

= 687

Step2:

LCM(3, 322) = 966

GCD(3, 322) = ( 3 x 322 ) / 966

= 3 / 322

= 3

Step3:

LCM(1, 413) = 413

GCD(1, 413) = ( 1 x 413 ) / 413

= 1 / 413

= 1

So, Greatest Common Divisor of 687, 981, 322, 413 is 1
