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

Apply this formula for all numbers.

Step1:

LCM(822, 978) = 133986

GCD(822, 978) = ( 822 x 978 ) / 133986

= 822 / 978

= 822

Step2:

LCM(6, 219) = 438

GCD(6, 219) = ( 6 x 219 ) / 438

= 6 / 219

= 6

So, Greatest Common Divisor of 822, 978, 219 is 3
