Given numbers are 489, 645, 585, 662

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

Apply this formula for all numbers.

Step1:

LCM(489, 645) = 105135

GCD(489, 645) = ( 489 x 645 ) / 105135

= 489 / 645

= 489

Step2:

LCM(3, 585) = 585

GCD(3, 585) = ( 3 x 585 ) / 585

= 3 / 585

= 3

Step3:

LCM(3, 662) = 1986

GCD(3, 662) = ( 3 x 662 ) / 1986

= 3 / 662

= 3

So, Greatest Common Divisor of 489, 645, 585, 662 is 1
