Given numbers are 442, 455, 439, 917

The list of prime factors of all numbers are

Prime factors of 442 are 2 x 13 x 17

Prime factors of 455 are 5 x 7 x 13

Prime factors of 439 are 439

Prime factors of 917 are 7 x 131

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

Given numbers are 442, 455, 439, 917

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

Apply this formula for all numbers.

Step1:

LCM(442, 455) = 15470

GCD(442, 455) = ( 442 x 455 ) / 15470

= 442 / 455

= 442

Step2:

LCM(13, 439) = 5707

GCD(13, 439) = ( 13 x 439 ) / 5707

= 13 / 439

= 13

Step3:

LCM(1, 917) = 917

GCD(1, 917) = ( 1 x 917 ) / 917

= 1 / 917

= 1

So, Greatest Common Divisor of 442, 455, 439, 917 is 1
