GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(810, 687) = 185490
GCD(810, 687) = ( 810 x 687 ) / 185490
= 810 / 687
= 810
Step2:
LCM(3, 417) = 417
GCD(3, 417) = ( 3 x 417 ) / 417
= 3 / 417
= 3
Step3:
LCM(3, 468) = 468
GCD(3, 468) = ( 3 x 468 ) / 468
= 3 / 468
= 3
So, Greatest Common Divisor of 810, 687, 417, 468 is 3
