The list of prime factors of all numbers are

Prime factors of 915 are 3 x 5 x 61

Prime factors of 261 are 3 x 3 x 29

Prime factors of 845 are 5 x 13 x 13

Prime factors of 447 are 3 x 149

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

Given numbers are 915, 261, 845, 447

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

Apply this formula for all numbers.

Step1:

LCM(915, 261) = 79605

GCD(915, 261) = ( 915 x 261 ) / 79605

= 915 / 261

= 915

Step2:

LCM(3, 845) = 2535

GCD(3, 845) = ( 3 x 845 ) / 2535

= 3 / 845

= 3

Step3:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

So, Greatest Common Divisor of 915, 261, 845, 447 is 1
