Given numbers are 323, 644, 852, 861

The list of prime factors of all numbers are

Prime factors of 323 are 17 x 19

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 852 are 2 x 2 x 3 x 71

Prime factors of 861 are 3 x 7 x 41

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

Given numbers are 323, 644, 852, 861

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

Apply this formula for all numbers.

Step1:

LCM(323, 644) = 208012

GCD(323, 644) = ( 323 x 644 ) / 208012

= 323 / 644

= 323

Step2:

LCM(1, 852) = 852

GCD(1, 852) = ( 1 x 852 ) / 852

= 1 / 852

= 1

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 323, 644, 852, 861 is 1
