# 56 and Level 2

56 is a composite number. 56 = 1 x 56, 2 x 28, 4 x 14, or 7 x 8. Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56. Prime factorization: 56 = 2 x 2 x 2 x 7, which can also be written 56 = 2³ x 7.

Sometimes 56 is a clue in the FIND THE FACTORS puzzles. Even though it has other factors, the only multiplication fact we use is 7 x 8 = 56.

This week’s puzzles are available in an excel file here. If you have a spreadsheet program on your computer, you can access it. If you enable editing in excel, you can type your answers directly onto the puzzle, and you can also easily print the puzzles.

1. Glad to have the answers for last week’s; the 404C puzzle was driving me and a friend crazy. Also I’m glad to have got it right.

• Those level 6 puzzles can be a challenge. Good for you and your friend for sticking with it until you got it right!

Yes, I made three and posted them. How are they the same? How are they different?
