Given numbers are 815, 446, 855, 448

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 446 are 2 x 223

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

Prime factors of 448 are 2 x 2 x 2 x 2 x 2 x 2 x 7

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

Given numbers are 815, 446, 855, 448

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

Apply this formula for all numbers.

Step1:

LCM(815, 446) = 363490

GCD(815, 446) = ( 815 x 446 ) / 363490

= 815 / 446

= 815

Step2:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

Step3:

LCM(1, 448) = 448

GCD(1, 448) = ( 1 x 448 ) / 448

= 1 / 448

= 1

So, Greatest Common Divisor of 815, 446, 855, 448 is 1
