Here is some information about the puzzle number, 1356:

  • 1356 is a composite number.
  • Prime factorization: 1356 = 2 × 2 × 3 × 113, which can be written 1356 = 2² × 3 × 113
  • 1356 has at least one exponent greater than 1 in its prime factorization so √1356 can be simplified. Taking the factor pair from the factor pair table below with the largest square number factor, we get √1356 = (√4)(√339) = 2√339

1350 Logic is at the Heart of This Puzzle

Today’s Puzzle:

By simply changing two clues of that recently published puzzle that I rejected, I was able to create a love-ly puzzle that can be solved entirely by logic. Can you figure out where to put the numbers from 1 to 12 in each of the four outlined areas that divide the puzzle into four equal sections? If you can, my heart might just skip a beat!

Factors of 1350:

  • 1350 is a composite number.
  • Prime factorization: 1350 = 2 × 3 × 3 × 3 × 5 × 5, which can be written 1350 = 2 × 3³ × 5²
  • The exponents in the prime factorization are 1, 3 and 2. Adding one to each and multiplying we get (1 + 1)(3 + 1)(2 + 1) = 2 × 4 × 3 = 24. Therefore 1350 has exactly 24 factors.
  • Factors of 1350: 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 27, 30, 45, 50, 54, 75, 90, 135, 150, 225, 270, 450, 675, 1350

Sum-Difference Puzzles:

6 has two factor pairs. One of those pairs adds up to 5, and the other one subtracts to 5. Put the factors in the appropriate boxes in the first puzzle.

1350 has twelve factor pairs. One of the factor pairs adds up to ­75, and a different one subtracts to 75. If you can identify those factor pairs, then you can solve the second puzzle!

The second puzzle is really just the first puzzle in disguise. Why would I say that?

More about the Number 1350:

1350 is the sum of consecutive prime numbers two ways:
It is the sum of the fourteen prime numbers from 67 to 131, and
673 + 677 = 1350

1350 is the hypotenuse of two Pythagorean triples:
810-1080-1350 which is (3-4-5) times 270

1348 Coloring Paula Krieg’s Polar Rose

Paula Beardell Krieg recently wrote about using Desmos to create designs that can be colored by hand or by computer programs like Paint. I like using Paint so with her permission I took a design she made and colored it so I could present it here in this post. I chose colors that make me think of spring because, frankly, I’m ready for winter to be over!

Now I’ll write a little bit about the number 1348:

If you’re not sure how to solve it, I explain how in this youtube video:

Here are some facts about the number 1347:

  • 1347 is a composite number.
  • Prime factorization: 1347 = 3 × 449
  • 1347 has no exponents greater than 1 in its prime factorization, so √1347 cannot be simplified.
  • The exponents in the prime factorization are 1, and 1. Adding one to each exponent and multiplying we get (1 + 1)(1 + 1) = 2 × 2 = 4. Therefore 1347 has exactly 4 factors.
  • The factors of 1347 are outlined with their factor pair partners in the graphic below.

1347 isn’t a Lucas number, but as OEIS.org reminds us, 1, 3, 4, 7 happens to be the first four Lucas numbers. Here’s why:
Start with 1, 3, then . . .
1 + 3 = 4
3 + 4 = 7
So what will be the next Lucas number?

1347 is the hypotenuse of a Pythagorean triple:
840-1053-1347 which is 3 times (280-351-449)

(1346÷2)×3 = 2019 Magic or Square?

I was inspired to make a 3 × 3 Magic Square where every number is different but the numbers in each row, column and diagonal added together equal the same number, 54:

I made it by taking a regular 3 × 3 Magic Square and adding 13 to each of its numbers.

What inspired me to do that? This magical tweet of a palindromic Magic Square for the Year 2019:

Yeah, I know my magic square isn’t quite as impressive. It might be more square than it is magic. It’s also less impressive than this number 2019 spelled out using fifty-one
4 × 4 Magic Squares.

Maybe you will be more impressed by this magic square that has 2019 as its Magic Sum?

I could make that magic sum because 2019 is divisible by 3. Why is 673 in the center? Because 2019÷3 = 673.

673 × 2 = 1346. I’m sharing these magic squares in this post I’ve numbered 1346. In case you haven’t figured it out (1346÷2)×3 = 2019. Happy New Year!
