    Step-by-step explanation:

    First find the prime factorization which is:

    3*11*31 = 1023

    if you multiply 3*11 you get 33

    and the other number left over in the equation is 31

    so you know that 31*33 = 1023 and they are consecutive odds so it works

    Step-by-step explanation:

    Let x = smaller odd number.

    Then the next greater consecutive odd number is x + 2.

    Their product is x (x + 2).

    Their product equals 1023.

    x (x + 2) = 1023

    x^2 + 2x = 1023

    x^2 + 2x - 1023 = 0

    (x + 33) (x - 31) = 0

    x + 33 = 0 or x - 31 = 0

    x = - 33 or x = 31

    We discard the negative answer since we are told both numbers are positive.

    x = 31

    x + 2 = 33

    The numbers are 31 and 33.
