How to calculate factors?
To be a factor of 44, a number must divide 44 exactly, leaving no remainder. In other words, when 44 is divided by this number, the quotient is a whole number. These factors, also known as divisors, define the structure of 44 and are key in understanding its mathematical properties.
Below, we outline how to calculate the factorization of 44 using four methods: basic factorization, prime factorization, the division method, or using GCD and LCM. We also include a detailed analysis of factor pairs and a factor tree to illustrate the breakdown.
Method 1: Basic Factorization
Basic Factorization is a method to find the factors of a number by systematically testing each whole number from 2 up to the number itself to see which ones divides with zero remainder (evenly). The process is somewhat time consuming if a number is high, that's why you should master divisibility rules, to make the process faster.
Here's the breakdown for 44:
| Divisor | Is it a factor of 44? | Verification |
|---|---|---|
| 1 | Yes, 1 is a factor of every number. | 1 × 44 = 44 |
| 2 | Yes, 44 is an even number so it's divisible by 2. | 2 × 22 = 44 |
| 3 | No, the sum of its digits (8) is not divisible by 3. | - |
| 4 | Yes, the last two digits (44) form a number divisible by 4. | 4 × 11 = 44 |
| 5 | No, last digit is 4, so not divisible by 5. | - |
| 6 | No, 44 is not divisible by both 2 and 3. | - |
| 7 | No, 44 divided by 7 leaves a remainder of 2. | - |
| 8 | No, the last three digits (44) do not form a number divisible by 8. | - |
| 9 | No, the sum of its digits (8) is not divisible by 9. | - |
| 10 | No, last digit is 4, so not divisible by 10. | - |
| 11 | Yes, the difference between sums of alternating digits (0) is divisible by 11. | 11 × 4 = 44 |
| 12 | No, 44 is not divisible by both 3 and 4. | - |
| ... | continue with all the other numbers. |
Method 2: Prime Factorization
Prime numbers are natural numbers greater than 1 that have no positive divisors other than 1 and themselves. This means a prime number cannot be formed by multiplying two smaller natural numbers. For example:
- 2 is a prime number because its only divisors are 1 and 2.
- 3 is prime for the same reason—it can only be divided evenly by 1 and 3.
- 4 is not prime because it can be divided by 1, 2, and 4.
- 5, 7, 11, and 13 are also prime numbers.
Prime numbers are fundamental in mathematics because they are the "building blocks" of whole numbers. Any natural number greater than 1 can be expressed as a product of prime numbers, which is known as its prime factorization.
How to do prime factorization of 44
You start by dividing 44 to each prime number, multiple times, until the remainder is 0. Then you move on to the next prime number. To save time, you should test with up to \( \sqrt44 \)
| Prime Number | Is it a factor of 44? | Verification |
|---|---|---|
| 2 | Yes, 44 is divisible by 2. | 44 ÷ 2 = 22, R0 |
| 2 | Yes, the result 22 is divisible by 2. | 22 ÷ 2 = 11, R0 |
| 2 | No, the result 11 is not divisible by 2. | - |
| 3 | No, 11 is not divisible by 3. | - |
| 11 | 11 is a prime number. | 11 is prime. |
Method 3: Division Method
The Division Method is a systematic approach to finding all the factors of a 44 by performing successive divisions. This method involves dividing 44 by every integer from 1 up to 44 and identifying the numbers that divide exactly without leaving a remainder. In the table below we've ommitted the numbers that don't divide 44, and only kept those that do:
| Divisor | Verification |
|---|---|
| 1 | 44 ÷ 1 = 44 |
| 2 | 44 ÷ 2 = 22 |
| 4 | 44 ÷ 4 = 11 |
| 11 | 44 ÷ 11 = 4 |
| 22 | 44 ÷ 22 = 2 |
| 44 | 44 ÷ 44 = 1 |
Using the division method, we calculated that factors of 44 are 1, 2, 4, 11, 22, 44.

Factor Pairs of 44 (Visualization)
Factor pairs of 44 are sets of two numbers that, when multiplied together, result in 44. Factor pairs are symmetric and mirror around the square root of 44, such as (1, 44) and (44, 1), and can be both positive and negative pairs as long as their product equals 44.
| Negative factor pairs | Positive factor pairs |
|---|---|
| (-1, -44) | (1, 44) |
| (-2, -22) | (2, 22) |
| (-4, -11) | (4, 11) |
All factor pairs of 44 are (1, 44), (2, 22), (4, 11), (-1, -44), (-2, -22), (-4, -11).
