The list of prime factors of all numbers are

Prime factors of 315 are 3 x 3 x 5 x 7

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

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 315, 858, 243, 448

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

Apply this formula for all numbers.

Step1:

LCM(315, 858) = 90090

GCD(315, 858) = ( 315 x 858 ) / 90090

= 315 / 858

= 315

Step2:

LCM(3, 243) = 243

GCD(3, 243) = ( 3 x 243 ) / 243

= 3 / 243

= 3

Step3:

LCM(3, 448) = 1344

GCD(3, 448) = ( 3 x 448 ) / 1344

= 3 / 448

= 3

So, Greatest Common Divisor of 315, 858, 243, 448 is 1
