Given numbers are 855, 861, 122, 547

The list of prime factors of all numbers are

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

Prime factors of 861 are 3 x 7 x 41

Prime factors of 122 are 2 x 61

Prime factors of 547 are 547

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

Given numbers are 855, 861, 122, 547

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

Apply this formula for all numbers.

Step1:

LCM(855, 861) = 245385

GCD(855, 861) = ( 855 x 861 ) / 245385

= 855 / 861

= 855

Step2:

LCM(3, 122) = 366

GCD(3, 122) = ( 3 x 122 ) / 366

= 3 / 122

= 3

Step3:

LCM(1, 547) = 547

GCD(1, 547) = ( 1 x 547 ) / 547

= 1 / 547

= 1

So, Greatest Common Divisor of 855, 861, 122, 547 is 1
