Given numbers are 489, 284, 147

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

Apply this formula for all numbers.

Step1:

LCM(489, 284) = 138876

GCD(489, 284) = ( 489 x 284 ) / 138876

= 489 / 284

= 489

Step2:

LCM(1, 147) = 147

GCD(1, 147) = ( 1 x 147 ) / 147

= 1 / 147

= 1

So, Greatest Common Divisor of 489, 284, 147 is 1
