Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 13,644,323, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 13,644,323 | |
| -1 | -13,644,323 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,644,323.
Example:
1 x 13,644,323 = 13,644,323
and
-1 x -13,644,323 = 13,644,323
Notice both answers equal 13,644,323
With that explanation out of the way, let's continue. Next, we take the number 13,644,323 and divide it by 2:
13,644,323 ÷ 2 = 6,822,161.5
If the quotient is a whole number, then 2 and 6,822,161.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 13,644,323 | |
| -1 | -13,644,323 |
Now, we try dividing 13,644,323 by 3:
13,644,323 ÷ 3 = 4,548,107.6667
If the quotient is a whole number, then 3 and 4,548,107.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 13,644,323 | |
| -1 | -13,644,323 |
Let's try dividing by 4:
13,644,323 ÷ 4 = 3,411,080.75
If the quotient is a whole number, then 4 and 3,411,080.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 13,644,323 | |
| -1 | 13,644,323 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 89 | 121 | 181 | 623 | 847 | 979 | 1,267 | 1,991 | 6,853 | 10,769 | 13,937 | 16,109 | 21,901 | 75,383 | 112,763 | 153,307 | 177,199 | 1,240,393 | 1,949,189 | 13,644,323 |
| -1 | -7 | -11 | -77 | -89 | -121 | -181 | -623 | -847 | -979 | -1,267 | -1,991 | -6,853 | -10,769 | -13,937 | -16,109 | -21,901 | -75,383 | -112,763 | -153,307 | -177,199 | -1,240,393 | -1,949,189 | -13,644,323 |
