Given numbers are 815, 113, 720, 800

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 113 are 113

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5

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

Given numbers are 815, 113, 720, 800

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

Apply this formula for all numbers.

Step1:

LCM(815, 113) = 92095

GCD(815, 113) = ( 815 x 113 ) / 92095

= 815 / 113

= 815

Step2:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

Step3:

LCM(1, 800) = 800

GCD(1, 800) = ( 1 x 800 ) / 800

= 1 / 800

= 1

So, Greatest Common Divisor of 815, 113, 720, 800 is 1
