    what is my number?
    Clue 1 My number is a multiple of 5,but it does not end in 5.
    - Multiples of 5 end in "5" and which other digit?
    - Can you identify 2 prime factors if the number ends in this digit?

    Clue 2 The prime factorization of my number is a string of three numbers.
    - From clue 1, we have already found two of the three prime factors. We need the third one.

    Clue 3 Two of the numbers in the prime factorizations are the same.
    - Therefore the third one must be a duplicate of one of the other two.
    - that leaves us two choices.

    Clue 4 My number is greater than the seventh square number.
    - out of the two choices, which one will make a number greater than 7²?
