The list of prime factors of all numbers are

Prime factors of 447 are 3 x 149

Prime factors of 687 are 3 x 229

Prime factors of 162 are 2 x 3 x 3 x 3 x 3

Prime factors of 871 are 13 x 67

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

Given numbers are 447, 687, 162, 871

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

Apply this formula for all numbers.

Step1:

LCM(447, 687) = 102363

GCD(447, 687) = ( 447 x 687 ) / 102363

= 447 / 687

= 447

Step2:

LCM(3, 162) = 162

GCD(3, 162) = ( 3 x 162 ) / 162

= 3 / 162

= 3

Step3:

LCM(3, 871) = 2613

GCD(3, 871) = ( 3 x 871 ) / 2613

= 3 / 871

= 3

So, Greatest Common Divisor of 447, 687, 162, 871 is 1
