Given numbers are 861, 348, 512, 865

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 348 are 2 x 2 x 3 x 29

Prime factors of 512 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 865 are 5 x 173

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

Given numbers are 861, 348, 512, 865

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

Apply this formula for all numbers.

Step1:

LCM(861, 348) = 99876

GCD(861, 348) = ( 861 x 348 ) / 99876

= 861 / 348

= 861

Step2:

LCM(3, 512) = 1536

GCD(3, 512) = ( 3 x 512 ) / 1536

= 3 / 512

= 3

Step3:

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

= 1 / 865

= 1

So, Greatest Common Divisor of 861, 348, 512, 865 is 1
