Given numbers are 408, 368, 309, 115

The list of prime factors of all numbers are

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 368 are 2 x 2 x 2 x 2 x 23

Prime factors of 309 are 3 x 103

Prime factors of 115 are 5 x 23

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

Given numbers are 408, 368, 309, 115

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

Apply this formula for all numbers.

Step1:

LCM(408, 368) = 18768

GCD(408, 368) = ( 408 x 368 ) / 18768

= 408 / 368

= 408

Step2:

LCM(8, 309) = 2472

GCD(8, 309) = ( 8 x 309 ) / 2472

= 8 / 309

= 8

Step3:

LCM(1, 115) = 115

GCD(1, 115) = ( 1 x 115 ) / 115

= 1 / 115

= 1

So, Greatest Common Divisor of 408, 368, 309, 115 is 1
