# 35 and Pushing an Easy Button

35 is a composite number. 35 = 1 x 35 or 5 x 7. Factors of 35: 1, 5, 7, 35. Prime factorization: 35 = 5 x 7.

When 35 is a clue in the FIND THE FACTORS puzzles, always use 5 and 7 as the factors.

This week’s level 4 puzzle has a couple of easy clues (1 & 81) that will give you a good start solving the puzzle.

Some of the rest of the clues may still be a challenge, but sometimes, once you’ve started something, you’ve already done the hardest part.

Can you write all the numbers from 1 to 10 in the top row and again in the first column so that the numbers you write become the factors of the given clues? There is only one solution. It’s easier if you use logic. It’s difficult and frustrating if you guess and check.

This week’s puzzles are also 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.

Here are the factors for last week’s level 4 snow shovel puzzle:

Below is a chart showing the steps I used to solve this puzzle using logic. The chart states what was written in the factor column and the factor row for each clue or set of clues.

The puzzle could have been solved using the clues in a little different order. Try it!

The more puzzles you work on, the easier they will become, with or without an easy button!
