Given numbers are 408, 310, 388, 869

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 310 are 2 x 5 x 31

Prime factors of 388 are 2 x 2 x 97

Prime factors of 869 are 11 x 79

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

Given numbers are 408, 310, 388, 869

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

Apply this formula for all numbers.

Step1:

LCM(408, 310) = 63240

GCD(408, 310) = ( 408 x 310 ) / 63240

= 408 / 310

= 408

Step2:

LCM(2, 388) = 388

GCD(2, 388) = ( 2 x 388 ) / 388

= 2 / 388

= 2

Step3:

LCM(2, 869) = 1738

GCD(2, 869) = ( 2 x 869 ) / 1738

= 2 / 869

= 2

So, Greatest Common Divisor of 408, 310, 388, 869 is 1
