Given numbers are 484, 216, 390, 810

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

Apply this formula for all numbers.

Step1:

LCM(484, 216) = 26136

GCD(484, 216) = ( 484 x 216 ) / 26136

= 484 / 216

= 484

Step2:

LCM(4, 390) = 780

GCD(4, 390) = ( 4 x 390 ) / 780

= 4 / 390

= 4

Step3:

LCM(2, 810) = 810

GCD(2, 810) = ( 2 x 810 ) / 810

= 2 / 810

= 2

So, Greatest Common Divisor of 484, 216, 390, 810 is 2
