Given numbers are 765, 825, 447, 721

The list of prime factors of all numbers are

Prime factors of 765 are 3 x 3 x 5 x 17

Prime factors of 825 are 3 x 5 x 5 x 11

Prime factors of 447 are 3 x 149

Prime factors of 721 are 7 x 103

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

Given numbers are 765, 825, 447, 721

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

Apply this formula for all numbers.

Step1:

LCM(765, 825) = 42075

GCD(765, 825) = ( 765 x 825 ) / 42075

= 765 / 825

= 765

Step2:

LCM(15, 447) = 2235

GCD(15, 447) = ( 15 x 447 ) / 2235

= 15 / 447

= 15

Step3:

LCM(3, 721) = 2163

GCD(3, 721) = ( 3 x 721 ) / 2163

= 3 / 721

= 3

So, Greatest Common Divisor of 765, 825, 447, 721 is 1
