Given numbers are 648, 585, 808, 822

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

Apply this formula for all numbers.

Step1:

LCM(648, 585) = 42120

GCD(648, 585) = ( 648 x 585 ) / 42120

= 648 / 585

= 648

Step2:

LCM(9, 808) = 7272

GCD(9, 808) = ( 9 x 808 ) / 7272

= 9 / 808

= 9

Step3:

LCM(1, 822) = 822

GCD(1, 822) = ( 1 x 822 ) / 822

= 1 / 822

= 1

So, Greatest Common Divisor of 648, 585, 808, 822 is 1
