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 13,404,445, 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 | 13,404,445 | |
| -1 | -13,404,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,404,445.
Example:
1 x 13,404,445 = 13,404,445
and
-1 x -13,404,445 = 13,404,445
Notice both answers equal 13,404,445
With that explanation out of the way, let's continue. Next, we take the number 13,404,445 and divide it by 2:
13,404,445 ÷ 2 = 6,702,222.5
If the quotient is a whole number, then 2 and 6,702,222.5 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 | 13,404,445 | |
| -1 | -13,404,445 |
Now, we try dividing 13,404,445 by 3:
13,404,445 ÷ 3 = 4,468,148.3333
If the quotient is a whole number, then 3 and 4,468,148.3333 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 | 13,404,445 | |
| -1 | -13,404,445 |
Let's try dividing by 4:
13,404,445 ÷ 4 = 3,351,111.25
If the quotient is a whole number, then 4 and 3,351,111.25 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 | 13,404,445 | |
| -1 | 13,404,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 71 | 305 | 355 | 619 | 3,095 | 4,331 | 21,655 | 37,759 | 43,949 | 188,795 | 219,745 | 2,680,889 | 13,404,445 |
| -1 | -5 | -61 | -71 | -305 | -355 | -619 | -3,095 | -4,331 | -21,655 | -37,759 | -43,949 | -188,795 | -219,745 | -2,680,889 | -13,404,445 |
