 This week’s puzzles and last week’s solutions: 10 Factors 2014-03-31 81 is a composite number and is 9 squared. 81 = 1 x 81, 3 x 27, or 9 x 9. Factors of 81: 1, 3, 9, 27, 81. Prime factorization: 81 = 3 x 3 x 3 x 3 which can also be written 3⁴. Since √81 = 9, a whole number, 81 is a perfect square. Sometimes 81 is a clue in the FIND THE FACTORS puzzles. Even though it has other factors, the only multiplication fact we use is 9 x 9 = 81. These are the integers which can be evenly divided into 81; they can be expressed as either individual factors or as factor pairs. In this case, we present them both ways. This is mathematical decomposition of a particular number. While usually a positive integer, take note of the comments below about negative numbers. What is the prime factorization of 81?A prime factorization is the result of factoring a number into a set of components which every member is a prime number. This is generally written by showing 81 as a product of its prime factors. For 81, this result would be: 81 = 3 x 3 x 3 x 3(this is also known as the prime factorisation; the smallest prime number in this series is described as the smallest prime factor)Yes! 81 is a composite number. It is the product of two positive numbers other than 1 and itself. Is 81 a square number?Yes! 81 is a square. Its square root is an integer, specifically 9.
