40 and M.C. Escher

40 is a composite number. 40 = 1 x 40, 2 x 20, 4 x 10, or 5 x 8. Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40. Prime factorization: 40 = 2 x 2 x 2 x 5, which can also be written 2³ x 5.

When 40 is a clue in the FIND THE FACTORS puzzles always use either 5 x 8 or 4 x 10. Only one of those combinations will work for any particular puzzle.

Today I share a blog post that was part of the 6-word challenge. I encourage other bloggers to accept the challenge on that post and send your finished product to the Figments of a DuTchess blog. Marion Driessen really will visit your blog if you do. She completed this beautiful jigsaw puzzle featuring the mathematically inspired artwork of M. C. Escher and relayed the challenge of putting it together using only six words!
