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 13,425,643, 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 | 13,425,643 | |
| -1 | -13,425,643 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,425,643.
Example:
1 x 13,425,643 = 13,425,643
and
-1 x -13,425,643 = 13,425,643
Notice both answers equal 13,425,643
With that explanation out of the way, let's continue. Next, we take the number 13,425,643 and divide it by 2:
13,425,643 ÷ 2 = 6,712,821.5
If the quotient is a whole number, then 2 and 6,712,821.5 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 | 13,425,643 | |
| -1 | -13,425,643 |
Now, we try dividing 13,425,643 by 3:
13,425,643 ÷ 3 = 4,475,214.3333
If the quotient is a whole number, then 3 and 4,475,214.3333 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 | 13,425,643 | |
| -1 | -13,425,643 |
Let's try dividing by 4:
13,425,643 ÷ 4 = 3,356,410.75
If the quotient is a whole number, then 4 and 3,356,410.75 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 | 13,425,643 | |
| -1 | 13,425,643 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 113 | 791 | 1,243 | 1,543 | 8,701 | 10,801 | 16,973 | 118,811 | 174,359 | 1,220,513 | 1,917,949 | 13,425,643 |
| -1 | -7 | -11 | -77 | -113 | -791 | -1,243 | -1,543 | -8,701 | -10,801 | -16,973 | -118,811 | -174,359 | -1,220,513 | -1,917,949 | -13,425,643 |
