Given numbers are 819, 238, 816, 505

The list of prime factors of all numbers are

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 238 are 2 x 7 x 17

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

Prime factors of 505 are 5 x 101

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

Given numbers are 819, 238, 816, 505

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

Apply this formula for all numbers.

Step1:

LCM(819, 238) = 27846

GCD(819, 238) = ( 819 x 238 ) / 27846

= 819 / 238

= 819

Step2:

LCM(7, 816) = 5712

GCD(7, 816) = ( 7 x 816 ) / 5712

= 7 / 816

= 7

Step3:

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

= 1 / 505

= 1

So, Greatest Common Divisor of 819, 238, 816, 505 is 1
