Given numbers are 440, 915, 441, 399

The list of prime factors of all numbers are

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 915 are 3 x 5 x 61

Prime factors of 441 are 3 x 3 x 7 x 7

Prime factors of 399 are 3 x 7 x 19

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

Given numbers are 440, 915, 441, 399

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

Apply this formula for all numbers.

Step1:

LCM(440, 915) = 80520

GCD(440, 915) = ( 440 x 915 ) / 80520

= 440 / 915

= 440

Step2:

LCM(5, 441) = 2205

GCD(5, 441) = ( 5 x 441 ) / 2205

= 5 / 441

= 5

Step3:

LCM(1, 399) = 399

GCD(1, 399) = ( 1 x 399 ) / 399

= 1 / 399

= 1

So, Greatest Common Divisor of 440, 915, 441, 399 is 1
