The list of prime factors of all numbers are

Prime factors of 789 are 3 x 263

Prime factors of 225 are 3 x 3 x 5 x 5

Prime factors of 801 are 3 x 3 x 89

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 789, 225, 801, 815

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

Apply this formula for all numbers.

Step1:

LCM(789, 225) = 59175

GCD(789, 225) = ( 789 x 225 ) / 59175

= 789 / 225

= 789

Step2:

LCM(3, 801) = 801

GCD(3, 801) = ( 3 x 801 ) / 801

= 3 / 801

= 3

Step3:

LCM(3, 815) = 2445

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

= 3 / 815

= 3

So, Greatest Common Divisor of 789, 225, 801, 815 is 1
