Given numbers are 861, 876, 389, 216

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 876 are 2 x 2 x 3 x 73

Prime factors of 389 are 389

Prime factors of 216 are 2 x 2 x 2 x 3 x 3 x 3

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

Given numbers are 861, 876, 389, 216

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

Apply this formula for all numbers.

Step1:

LCM(861, 876) = 251412

GCD(861, 876) = ( 861 x 876 ) / 251412

= 861 / 876

= 861

Step2:

LCM(3, 389) = 1167

GCD(3, 389) = ( 3 x 389 ) / 1167

= 3 / 389

= 3

Step3:

LCM(1, 216) = 216

GCD(1, 216) = ( 1 x 216 ) / 216

= 1 / 216

= 1

So, Greatest Common Divisor of 861, 876, 389, 216 is 1
