Given numbers are 489, 552, 18, 386

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

Apply this formula for all numbers.

Step1:

LCM(489, 552) = 89976

GCD(489, 552) = ( 489 x 552 ) / 89976

= 489 / 552

= 489

Step2:

LCM(3, 18) = 18

GCD(3, 18) = ( 3 x 18 ) / 18

= 3 / 18

= 3

Step3:

LCM(3, 386) = 1158

GCD(3, 386) = ( 3 x 386 ) / 1158

= 3 / 386

= 3

So, Greatest Common Divisor of 489, 552, 18, 386 is 1
