  1. 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?

  8. Guys it's 50 because the prime factorization is 5*5*2=50 it fits all the clues.

  11. It's 50 because it's greater than the seventh square and it doesn't end in zero so if a multiple is 5 than it has to end in 5 and not zero so it's not 30.
