Given numbers are 489, 570, 668, 619

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

Apply this formula for all numbers.

Step1:

LCM(489, 570) = 92910

GCD(489, 570) = ( 489 x 570 ) / 92910

= 489 / 570

= 489

Step2:

LCM(3, 668) = 2004

GCD(3, 668) = ( 3 x 668 ) / 2004

= 3 / 668

= 3

Step3:

LCM(1, 619) = 619

GCD(1, 619) = ( 1 x 619 ) / 619

= 1 / 619

= 1

So, Greatest Common Divisor of 489, 570, 668, 619 is 1
