Given numbers are 489, 885, 747, 571

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

Apply this formula for all numbers.

Step1:

LCM(489, 885) = 144255

GCD(489, 885) = ( 489 x 885 ) / 144255

= 489 / 885

= 489

Step2:

LCM(3, 747) = 747

GCD(3, 747) = ( 3 x 747 ) / 747

= 3 / 747

= 3

Step3:

LCM(3, 571) = 1713

GCD(3, 571) = ( 3 x 571 ) / 1713

= 3 / 571

= 3

So, Greatest Common Divisor of 489, 885, 747, 571 is 1
