Given numbers are 861, 852, 321, 380

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

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

Prime factors of 321 are 3 x 107

Prime factors of 380 are 2 x 2 x 5 x 19

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

Given numbers are 861, 852, 321, 380

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

Apply this formula for all numbers.

Step1:

LCM(861, 852) = 244524

GCD(861, 852) = ( 861 x 852 ) / 244524

= 861 / 852

= 861

Step2:

LCM(3, 321) = 321

GCD(3, 321) = ( 3 x 321 ) / 321

= 3 / 321

= 3

Step3:

LCM(3, 380) = 1140

GCD(3, 380) = ( 3 x 380 ) / 1140

= 3 / 380

= 3

So, Greatest Common Divisor of 861, 852, 321, 380 is 1
