Given numbers are 630, 878, 718, 815

The list of prime factors of all numbers are

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 878 are 2 x 439

Prime factors of 718 are 2 x 359

Prime factors of 815 are 5 x 163

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

Given numbers are 630, 878, 718, 815

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

Apply this formula for all numbers.

Step1:

LCM(630, 878) = 276570

GCD(630, 878) = ( 630 x 878 ) / 276570

= 630 / 878

= 630

Step2:

LCM(2, 718) = 718

GCD(2, 718) = ( 2 x 718 ) / 718

= 2 / 718

= 2

Step3:

LCM(2, 815) = 1630

GCD(2, 815) = ( 2 x 815 ) / 1630

= 2 / 815

= 2

So, Greatest Common Divisor of 630, 878, 718, 815 is 1
