So, the GCD (815, 105, 816, 834) = 1.

Given numbers are 815, 105, 816, 834

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 105 are 3 x 5 x 7

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

Prime factors of 834 are 2 x 3 x 139

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

Given numbers are 815, 105, 816, 834

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

Apply this formula for all numbers.

Step1:

LCM(815, 105) = 17115

GCD(815, 105) = ( 815 x 105 ) / 17115

= 815 / 105

= 815

Step2:

LCM(5, 816) = 4080

GCD(5, 816) = ( 5 x 816 ) / 4080

= 5 / 816

= 5

Step3:

LCM(1, 834) = 834

GCD(1, 834) = ( 1 x 834 ) / 834

= 1 / 834

= 1

So, Greatest Common Divisor of 815, 105, 816, 834 is 1
