Given numbers are 390, 390, 871, 306

The list of prime factors of all numbers are

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

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

Prime factors of 871 are 13 x 67

Prime factors of 306 are 2 x 3 x 3 x 17

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

Given numbers are 390, 390, 871, 306

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

Apply this formula for all numbers.

Step1:

LCM(390, 390) = 390

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

= 390 / 390

= 390

Step2:

LCM(390, 871) = 26130

GCD(390, 871) = ( 390 x 871 ) / 26130

= 390 / 871

= 390

Step3:

LCM(13, 306) = 3978

GCD(13, 306) = ( 13 x 306 ) / 3978

= 13 / 306

= 13

So, Greatest Common Divisor of 390, 390, 871, 306 is 1
