Given numbers are 815, 663, 481, 813

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 663 are 3 x 13 x 17

Prime factors of 481 are 13 x 37

Prime factors of 813 are 3 x 271

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

Given numbers are 815, 663, 481, 813

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

Apply this formula for all numbers.

Step1:

LCM(815, 663) = 540345

GCD(815, 663) = ( 815 x 663 ) / 540345

= 815 / 663

= 815

Step2:

LCM(1, 481) = 481

GCD(1, 481) = ( 1 x 481 ) / 481

= 1 / 481

= 1

Step3:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

So, Greatest Common Divisor of 815, 663, 481, 813 is 1
