Given numbers are 861, 114, 855, 170

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 114 are 2 x 3 x 19

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 170 are 2 x 5 x 17

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

Given numbers are 861, 114, 855, 170

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

Apply this formula for all numbers.

Step1:

LCM(861, 114) = 32718

GCD(861, 114) = ( 861 x 114 ) / 32718

= 861 / 114

= 861

Step2:

LCM(3, 855) = 855

GCD(3, 855) = ( 3 x 855 ) / 855

= 3 / 855

= 3

Step3:

LCM(3, 170) = 510

GCD(3, 170) = ( 3 x 170 ) / 510

= 3 / 170

= 3

So, Greatest Common Divisor of 861, 114, 855, 170 is 1
