Given numbers are 815, 706, 721, 273

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 706 are 2 x 353

Prime factors of 721 are 7 x 103

Prime factors of 273 are 3 x 7 x 13

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

Given numbers are 815, 706, 721, 273

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

Apply this formula for all numbers.

Step1:

LCM(815, 706) = 575390

GCD(815, 706) = ( 815 x 706 ) / 575390

= 815 / 706

= 815

Step2:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

Step3:

LCM(1, 273) = 273

GCD(1, 273) = ( 1 x 273 ) / 273

= 1 / 273

= 1

So, Greatest Common Divisor of 815, 706, 721, 273 is 1
