Given numbers are 816, 225, 28, 823

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

Apply this formula for all numbers.

Step1:

LCM(816, 225) = 61200

GCD(816, 225) = ( 816 x 225 ) / 61200

= 816 / 225

= 816

Step2:

LCM(3, 28) = 84

GCD(3, 28) = ( 3 x 28 ) / 84

= 3 / 28

= 3

Step3:

LCM(1, 823) = 823

GCD(1, 823) = ( 1 x 823 ) / 823

= 1 / 823

= 1

So, Greatest Common Divisor of 816, 225, 28, 823 is 1
