Given numbers are 915, 561, 344, 966

The list of prime factors of all numbers are

Prime factors of 915 are 3 x 5 x 61

Prime factors of 561 are 3 x 11 x 17

Prime factors of 344 are 2 x 2 x 2 x 43

Prime factors of 966 are 2 x 3 x 7 x 23

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

Given numbers are 915, 561, 344, 966

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

Apply this formula for all numbers.

Step1:

LCM(915, 561) = 171105

GCD(915, 561) = ( 915 x 561 ) / 171105

= 915 / 561

= 915

Step2:

LCM(3, 344) = 1032

GCD(3, 344) = ( 3 x 344 ) / 1032

= 3 / 344

= 3

Step3:

LCM(1, 966) = 966

GCD(1, 966) = ( 1 x 966 ) / 966

= 1 / 966

= 1

So, Greatest Common Divisor of 915, 561, 344, 966 is 1
