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

Apply this formula for all numbers.

Step1:

LCM(978, 812) = 397068

GCD(978, 812) = ( 978 x 812 ) / 397068

= 978 / 812

= 978

Step2:

LCM(2, 822) = 822

GCD(2, 822) = ( 2 x 822 ) / 822

= 2 / 822

= 2

So, Greatest Common Divisor of 978, 812, 822 is 2
