    Answer:You cannot factor every real number. You can only factor integers.

    Just reduce it step by step: 45000=(45)(1000)=(5)(9)(10)(10)(10)=(2^3)(3^2)(5^4)

    What I learned in elementary school is to divide successively by all primes until you get 1 in the quotient.
    45000 / 2
    22500 / 2
    11250 / 2
    5625 / 3
    1875 / 3
    625 / 5
    125 / 5
    25 / 5
    5 / 5
    1
    [tex]45000 =2^3*3^2*5^4[/tex]

    elaborating on SGT's and Galileo's, all the factors of 4500 are any combinations of their prime factorizations. maybe you got that.. but some kids don't...

    at any rate, this sounds more like a homework problem than a teaser...
