Given numbers are 310, 721, 815, 320

The list of prime factors of all numbers are

Prime factors of 310 are 2 x 5 x 31

Prime factors of 721 are 7 x 103

Prime factors of 815 are 5 x 163

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 310, 721, 815, 320

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

Apply this formula for all numbers.

Step1:

LCM(310, 721) = 223510

GCD(310, 721) = ( 310 x 721 ) / 223510

= 310 / 721

= 310

Step2:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

Step3:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

So, Greatest Common Divisor of 310, 721, 815, 320 is 1
