Given numbers are 320, 130, 870, 399

The list of prime factors of all numbers are

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 130 are 2 x 5 x 13

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 399 are 3 x 7 x 19

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

Given numbers are 320, 130, 870, 399

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

Apply this formula for all numbers.

Step1:

LCM(320, 130) = 4160

GCD(320, 130) = ( 320 x 130 ) / 4160

= 320 / 130

= 320

Step2:

LCM(10, 870) = 870

GCD(10, 870) = ( 10 x 870 ) / 870

= 10 / 870

= 10

Step3:

LCM(10, 399) = 3990

GCD(10, 399) = ( 10 x 399 ) / 3990

= 10 / 399

= 10

So, Greatest Common Divisor of 320, 130, 870, 399 is 1
