Given numbers are 861, 430, 845, 891

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 430 are 2 x 5 x 43

Prime factors of 845 are 5 x 13 x 13

Prime factors of 891 are 3 x 3 x 3 x 3 x 11

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

Given numbers are 861, 430, 845, 891

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

Apply this formula for all numbers.

Step1:

LCM(861, 430) = 370230

GCD(861, 430) = ( 861 x 430 ) / 370230

= 861 / 430

= 861

Step2:

LCM(1, 845) = 845

GCD(1, 845) = ( 1 x 845 ) / 845

= 1 / 845

= 1

Step3:

LCM(1, 891) = 891

GCD(1, 891) = ( 1 x 891 ) / 891

= 1 / 891

= 1

So, Greatest Common Divisor of 861, 430, 845, 891 is 1
