Nine: 11, 13, 15, 17, 19, 23, 25, 27 and 29.
20 numbers from 1 to 50 are relatively prime with 50. They are 1, 3, 7, 9, 11, 13, 17, 19, 21, 23, 27, 29, 31, 33, 37, 39, 41, 43, 47 and 49. The only factor any of those share with 50 is 1, making them relatively prime with 50.
The prime numbers (factors) of 1000 are: 2 and 5
