Given numbers are 489, 842, 648, 294

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

Apply this formula for all numbers.

Step1:

LCM(489, 842) = 411738

GCD(489, 842) = ( 489 x 842 ) / 411738

= 489 / 842

= 489

Step2:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

Step3:

LCM(1, 294) = 294

GCD(1, 294) = ( 1 x 294 ) / 294

= 1 / 294

= 1

So, Greatest Common Divisor of 489, 842, 648, 294 is 1
