Given numbers are 609, 912, 391, 905

The list of prime factors of all numbers are

Prime factors of 609 are 3 x 7 x 29

Prime factors of 912 are 2 x 2 x 2 x 2 x 3 x 19

Prime factors of 391 are 17 x 23

Prime factors of 905 are 5 x 181

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

Given numbers are 609, 912, 391, 905

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

Apply this formula for all numbers.

Step1:

LCM(609, 912) = 185136

GCD(609, 912) = ( 609 x 912 ) / 185136

= 609 / 912

= 609

Step2:

LCM(3, 391) = 1173

GCD(3, 391) = ( 3 x 391 ) / 1173

= 3 / 391

= 3

Step3:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

So, Greatest Common Divisor of 609, 912, 391, 905 is 1
