The factors of 34 are: 1, 2, 17, 34 The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
The prime factors of 51 are 3 and 17. Once you add itself and one, you have all the factors. (1,3,17,51)
The factors of 68 are 1, 2, 4, 17, 34 and 68. None of them add up to 15 unless you use a bunch of ones and twos. If that's -68, you can use 17 and -2.
They are 1 and 17 because 17 is a prime number which has only two factors
-43
factors of 30 that add to 17 are 2 and 15
17 over 60 cannot be simplified because 17 is a prime number and has no factors in common with 60.

First you should list all the factors of 60: 1,2,3,4,5,6,10,12,15,20,30 Now we can go through each of the factors and see if we can get another factor to add to 17 with it: For 1 , we would need another factor of 16, which we don't have. Trying 2, we would need 15, which IS a factor. So 2 and 15 would work.
12 and 5
Only the number 1.

An hour is 60 minutes, so multiply 23 by 60 to get 1380, then add in the 17 minutes to get 1397 minutes.
