Given numbers are 390, 912, 612, 805

The list of prime factors of all numbers are

Prime factors of 390 are 2 x 3 x 5 x 13

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

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 805 are 5 x 7 x 23

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

Given numbers are 390, 912, 612, 805

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

Apply this formula for all numbers.

Step1:

LCM(390, 912) = 59280

GCD(390, 912) = ( 390 x 912 ) / 59280

= 390 / 912

= 390

Step2:

LCM(6, 612) = 612

GCD(6, 612) = ( 6 x 612 ) / 612

= 6 / 612

= 6

Step3:

LCM(6, 805) = 4830

GCD(6, 805) = ( 6 x 805 ) / 4830

= 6 / 805

= 6

So, Greatest Common Divisor of 390, 912, 612, 805 is 1
