Given numbers are 470, 921, 489

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

Apply this formula for all numbers.

Step1:

LCM(470, 921) = 432870

GCD(470, 921) = ( 470 x 921 ) / 432870

= 470 / 921

= 470

Step2:

LCM(1, 489) = 489

GCD(1, 489) = ( 1 x 489 ) / 489

= 1 / 489

= 1

So, Greatest Common Divisor of 470, 921, 489 is 1
