Given numbers are 421, 810, 398, 683

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

Apply this formula for all numbers.

Step1:

LCM(421, 810) = 341010

GCD(421, 810) = ( 421 x 810 ) / 341010

= 421 / 810

= 421

Step2:

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

= 1 / 398

= 1

Step3:

LCM(1, 683) = 683

GCD(1, 683) = ( 1 x 683 ) / 683

= 1 / 683

= 1

So, Greatest Common Divisor of 421, 810, 398, 683 is 1
