If the product of a multiplication problem is 144, this means that 144 has multiple factors. Factors are integers that can be multiplied together to give the product.
Here are some important points about the factors of 144:
-
Factor Pairs: The factors of 144 can be paired to multiply to 144. Some factor pairs include:
- \(1 \times 144\)
- \(2 \times 72\)
- \(3 \times 48\)
- \(4 \times 36\)
- \(6 \times 24\)
- \(8 \times 18\)
- \(9 \times 16\)
- \(12 \times 12\)
-
Total Number of Factors: To find the total number of factors, you can use the prime factorization of 144. The prime factorization is:
- \(144 = 2^4 \times 3^2\) Using the rule that if a number is factored into \(p_1^{e_1} \times p_2^{e_2} \), the total number of factors is \((e_1 + 1)(e_2 + 1)\), the total number of factors of 144 is:
- \((4 + 1)(2 + 1) = 5 \times 3 = 15\)
-
Divisibility: All factors of 144 will evenly divide into 144 without leaving a remainder.
-
Evenness: Since 144 is an even number, all of its factors will also retain some even properties. Specifically, it will have both even and odd factors.
-
Square Factor: 144 is a perfect square since \(12 \times 12 = 144\).
-
Positive and Negative Factors: In addition to the positive factors, each positive factor has a corresponding negative factor. So, -1, -2, -3, etc., are also factors.
In summary, the factors of 144 include: \(1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144\) (and their negatives), with a total of 15 factors overall.
