Given numbers are 489, 908, 643, 227

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

Apply this formula for all numbers.

Step1:

LCM(489, 908) = 444012

GCD(489, 908) = ( 489 x 908 ) / 444012

= 489 / 908

= 489

Step2:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

Step3:

LCM(1, 227) = 227

GCD(1, 227) = ( 1 x 227 ) / 227

= 1 / 227

= 1

So, Greatest Common Divisor of 489, 908, 643, 227 is 1
