Given numbers are 870, 389, 904, 550

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 904 are 2 x 2 x 2 x 113

Prime factors of 550 are 2 x 5 x 5 x 11

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

Given numbers are 870, 389, 904, 550

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, 904) = 904

GCD(1, 904) = ( 1 x 904 ) / 904

= 1 / 904

= 1

Step3:

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

= 1 / 550

= 1

So, Greatest Common Divisor of 870, 389, 904, 550 is 1
