    Question What do these numbers have in common, please?

    There is a Venn Diagram

    first set of #s are:
    4, 36, 25, 9, 49 (but 24 & 6 are not in the Venn diagram)

    second set of #s are:
    25, 9, 49, 11, 29 (but 24 & 6 are not in the Venn diagram)


    Choice of answer is:
    odd numbers
    Even numbers
    Numbers with 2 as a factor
    Numbers with exactly 2 different factors
    Numbers with 5 as a afctor
    Prime Numbers
    Composite Numbers
    Numbers iwth More than 3 Factors
    Numbers with 4 as a factor
    Square Numbers
    Numbers with fewer than 4 factors
    Numbers with 3 as a factor
    Numbers with 7 as a factor.

    I am required to have an answer for the first set of #s and another answer for the 2nd set of #s.

    I have tried a process of elimination but can't get the answer out. I would appreciate advice. Thank you.

    Hint on the first set: 24 and 6 are not perfect squares.

    Hint on the second set: 24 and 6 are even.

    What?

    The first set is all squares.


    The second set is all odd.


    Can you explain what you mean by, "24&6 are not in the Venn Diagram?" I have a feeling that's important.

    In response...

    the left circle has 4, 36 in it
    the right circle has 11, 29 in it
    in the middle where the circles overlap there is 25, 9, 49

    Outside the circles are 24, 6

    Hope this helps.
