Given numbers are 861, 178, 122, 468

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 178 are 2 x 89

Prime factors of 122 are 2 x 61

Prime factors of 468 are 2 x 2 x 3 x 3 x 13

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

Given numbers are 861, 178, 122, 468

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

Apply this formula for all numbers.

Step1:

LCM(861, 178) = 153258

GCD(861, 178) = ( 861 x 178 ) / 153258

= 861 / 178

= 861

Step2:

LCM(1, 122) = 122

GCD(1, 122) = ( 1 x 122 ) / 122

= 1 / 122

= 1

Step3:

LCM(1, 468) = 468

GCD(1, 468) = ( 1 x 468 ) / 468

= 1 / 468

= 1

So, Greatest Common Divisor of 861, 178, 122, 468 is 1
