Given numbers are 489, 942, 342, 670

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

Apply this formula for all numbers.

Step1:

LCM(489, 942) = 153546

GCD(489, 942) = ( 489 x 942 ) / 153546

= 489 / 942

= 489

Step2:

LCM(3, 342) = 342

GCD(3, 342) = ( 3 x 342 ) / 342

= 3 / 342

= 3

Step3:

LCM(3, 670) = 2010

GCD(3, 670) = ( 3 x 670 ) / 2010

= 3 / 670

= 3

So, Greatest Common Divisor of 489, 942, 342, 670 is 1
