692 Happy Thanksgiving!

  • 692 is a composite number.
  • Prime factorization: 692 = 2 x 2 x 173, which can be written 692 = (2^2) x 173
  • The exponents in the prime factorization are 2 and 1. Adding one to each and multiplying we get (2 + 1)(1 + 1) = 3 x 2  = 6. Therefore 692 has exactly 6 factors.
  • Factors of 692: 1, 2, 4, 173, 346, 692
  • Factor pairs: 692 = 1 x 692, 2 x 346, or 4 x 173
  • Taking the factor pair with the largest square number factor, we get √692 = (√4)(√173) = 2√173 ≈ 26.30589.

Today is Thanksgiving in the United States. Regardless of where we live, there are reasons to be grateful today and every other day. Corrie ten Boom was grateful even when her circumstances were horrible. Here’s a Thanksgiving themed puzzle to solve:

Here’s a little more about the number 692:

Because 173 is one of its factors, 692 is the hypotenuse of Pythagorean triple 208-660-692. What is the greatest common factor of those three numbers?

692 is a palindrome in 2 bases:

  • 221122 BASE 3; note that 2(243) + 2(81) + 1(27) + 1(9) + 2(3) + 2(1) = 692
  • 848 BASE 9; note that 8(81) + 4(9) + 8(1) = 692

11 Counting Blessings

  • 11 is a prime number.
  • Prime factorization: 11 is prime.
  • The exponent of prime number 11 is 1. Adding 1 to that exponent we get (1 + 1) = 2. Therefore 11 has exactly 2 factors.
  • Factors of 11: 1, 11
  • Factor pairs: 11 = 1 x 11
  • 11 has no square factors that allow its square root to be simplified. √11 ≈ 3.31662.

How do we know that 11 is a prime number? If 11 were not a prime number, then it would be divisible by at least one prime number less than or equal to √11 ≈ 3.3. Since 11 cannot be divided evenly by 2 or 3, we know that 11 is a prime number.

Sometimes 11 is a clue in the FIND THE FACTORS 1 – 12 puzzles, and the factors are always 1 and 11.

I have more blessings than I could ever completely count. This is not the place where I will attempt to name them one by one, but I wonder: is the number of blessings that I or anyone else has finite or infinite? Even being able to ponder that question is a blessing. In the last few years in the United States, much of the gratitude part of Thanksgiving has gotten lost in commercialism. Therefore, for some people the number of blessings may be finite and easily measured by counting things. Some of those blessings may be more imaginary than real. Nevertheless, there are still people who can see the hand of God all around them. For them the number of blessings is infinite. Likewise those who rely on the Savior and His infinite atonement have an infinite number of blessings. As I count blessings, I find that some of them are prime, and some are a composite of several blessings working together. Some blessings are rather odd while others are shared evenly. I am grateful for many positive events in my life, but even negative experiences are blessings because they have helped me to grow.

The following blessings may seem trivial, but I am grateful that WordPress has given me a way to share the Find the Factors puzzles not only as jpg pictures, but also in an excel file.  The puzzles have been a blessing to me, and I want to show my gratitude by sharing them with other people. I am grateful for the blogs I follow. They challenge me, entertain me, and teach me so much. I am also thankful to everyone who has looked at my blog.
