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 13,444,445, 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 | 13,444,445 | |
| -1 | -13,444,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,444,445.
Example:
1 x 13,444,445 = 13,444,445
and
-1 x -13,444,445 = 13,444,445
Notice both answers equal 13,444,445
With that explanation out of the way, let's continue. Next, we take the number 13,444,445 and divide it by 2:
13,444,445 ÷ 2 = 6,722,222.5
If the quotient is a whole number, then 2 and 6,722,222.5 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 | 13,444,445 | |
| -1 | -13,444,445 |
Now, we try dividing 13,444,445 by 3:
13,444,445 ÷ 3 = 4,481,481.6667
If the quotient is a whole number, then 3 and 4,481,481.6667 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 | 13,444,445 | |
| -1 | -13,444,445 |
Let's try dividing by 4:
13,444,445 ÷ 4 = 3,361,111.25
If the quotient is a whole number, then 4 and 3,361,111.25 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 | 13,444,445 | |
| -1 | 13,444,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 281 | 1,367 | 1,405 | 1,967 | 6,835 | 9,569 | 9,835 | 47,845 | 384,127 | 1,920,635 | 2,688,889 | 13,444,445 |
| -1 | -5 | -7 | -35 | -281 | -1,367 | -1,405 | -1,967 | -6,835 | -9,569 | -9,835 | -47,845 | -384,127 | -1,920,635 | -2,688,889 | -13,444,445 |
