Given numbers are 870, 389, 342, 395

The list of prime factors of all numbers are

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

Prime factors of 389 are 389

Prime factors of 342 are 2 x 3 x 3 x 19

Prime factors of 395 are 5 x 79

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

Given numbers are 870, 389, 342, 395

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

Apply this formula for all numbers.

Step1:

LCM(870, 389) = 338430

GCD(870, 389) = ( 870 x 389 ) / 338430

= 870 / 389

= 870

Step2:

LCM(1, 342) = 342

GCD(1, 342) = ( 1 x 342 ) / 342

= 1 / 342

= 1

Step3:

LCM(1, 395) = 395

GCD(1, 395) = ( 1 x 395 ) / 395

= 1 / 395

= 1

So, Greatest Common Divisor of 870, 389, 342, 395 is 1
