Given numbers are 875, 430, 861, 823

The list of prime factors of all numbers are

Prime factors of 875 are 5 x 5 x 5 x 7

Prime factors of 430 are 2 x 5 x 43

Prime factors of 861 are 3 x 7 x 41

Prime factors of 823 are 823

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

Given numbers are 875, 430, 861, 823

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

Apply this formula for all numbers.

Step1:

LCM(875, 430) = 75250

GCD(875, 430) = ( 875 x 430 ) / 75250

= 875 / 430

= 875

Step2:

LCM(5, 861) = 4305

GCD(5, 861) = ( 5 x 861 ) / 4305

= 5 / 861

= 5

Step3:

LCM(1, 823) = 823

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

= 1 / 823

= 1

So, Greatest Common Divisor of 875, 430, 861, 823 is 1
