Given numbers are 823, 861, 408, 834

The list of prime factors of all numbers are

Prime factors of 823 are 823

Prime factors of 861 are 3 x 7 x 41

Prime factors of 408 are 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 823, 861, 408, 834

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

Apply this formula for all numbers.

Step1:

LCM(823, 861) = 708603

GCD(823, 861) = ( 823 x 861 ) / 708603

= 823 / 861

= 823

Step2:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

Step3:

LCM(1, 834) = 834

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

= 1 / 834

= 1

So, Greatest Common Divisor of 823, 861, 408, 834 is 1
