Given numbers are 489, 649, 978, 110

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

Apply this formula for all numbers.

Step1:

LCM(489, 649) = 317361

GCD(489, 649) = ( 489 x 649 ) / 317361

= 489 / 649

= 489

Step2:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

Step3:

LCM(1, 110) = 110

GCD(1, 110) = ( 1 x 110 ) / 110

= 1 / 110

= 1

So, Greatest Common Divisor of 489, 649, 978, 110 is 1
