The list of prime factors of all numbers are

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

Prime factors of 498 are 2 x 3 x 83

Prime factors of 281 are 281

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 816, 498, 281, 640

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

Apply this formula for all numbers.

Step1:

LCM(816, 498) = 67728

GCD(816, 498) = ( 816 x 498 ) / 67728

= 816 / 498

= 816

Step2:

LCM(6, 281) = 1686

GCD(6, 281) = ( 6 x 281 ) / 1686

= 6 / 281

= 6

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 816, 498, 281, 640 is 1
