Given numbers are 489, 790, 558, 839

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

Apply this formula for all numbers.

Step1:

LCM(489, 790) = 386310

GCD(489, 790) = ( 489 x 790 ) / 386310

= 489 / 790

= 489

Step2:

LCM(1, 558) = 558

GCD(1, 558) = ( 1 x 558 ) / 558

= 1 / 558

= 1

Step3:

LCM(1, 839) = 839

GCD(1, 839) = ( 1 x 839 ) / 839

= 1 / 839

= 1

So, Greatest Common Divisor of 489, 790, 558, 839 is 1
