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

Apply this formula for all numbers.

Step1:

LCM(822, 862) = 354282

GCD(822, 862) = ( 822 x 862 ) / 354282

= 822 / 862

= 822

Step2:

LCM(2, 404) = 404

GCD(2, 404) = ( 2 x 404 ) / 404

= 2 / 404

= 2

Step3:

LCM(2, 578) = 578

GCD(2, 578) = ( 2 x 578 ) / 578

= 2 / 578

= 2

So, Greatest Common Divisor of 822, 862, 404, 578 is 2
