what about 2x3x5x7x11x13x17x19....up to 10 prime numbers...that will get you more than 10
you can see from the first few, you also as a side, you get 6,10,14...15,21,33,...

If you want exactly 10 divisors, then the number will have to be a product of two primes, one raised to the 1st power, and the other raised to the 4th power.
For example,
567 = 3^4 * 7^1
Its factors are
1 3 7 9 21 27 63 81 189 567
