Given numbers are 711, 681, 720, 815

The list of prime factors of all numbers are

Prime factors of 711 are 3 x 3 x 79

Prime factors of 681 are 3 x 227

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

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 711, 681, 720, 815

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

Apply this formula for all numbers.

Step1:

LCM(711, 681) = 161397

GCD(711, 681) = ( 711 x 681 ) / 161397

= 711 / 681

= 711

Step2:

LCM(3, 720) = 720

GCD(3, 720) = ( 3 x 720 ) / 720

= 3 / 720

= 3

Step3:

LCM(3, 815) = 2445

GCD(3, 815) = ( 3 x 815 ) / 2445

= 3 / 815

= 3

So, Greatest Common Divisor of 711, 681, 720, 815 is 1
