Given numbers are 978, 798, 622, 489

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

Apply this formula for all numbers.

Step1:

LCM(978, 798) = 130074

GCD(978, 798) = ( 978 x 798 ) / 130074

= 978 / 798

= 978

Step2:

LCM(6, 622) = 1866

GCD(6, 622) = ( 6 x 622 ) / 1866

= 6 / 622

= 6

Step3:

LCM(2, 489) = 978

GCD(2, 489) = ( 2 x 489 ) / 978

= 2 / 489

= 2

So, Greatest Common Divisor of 978, 798, 622, 489 is 1
