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 13,192,535, 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 | 13,192,535 | |
| -1 | -13,192,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,192,535.
Example:
1 x 13,192,535 = 13,192,535
and
-1 x -13,192,535 = 13,192,535
Notice both answers equal 13,192,535
With that explanation out of the way, let's continue. Next, we take the number 13,192,535 and divide it by 2:
13,192,535 ÷ 2 = 6,596,267.5
If the quotient is a whole number, then 2 and 6,596,267.5 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 | 13,192,535 | |
| -1 | -13,192,535 |
Now, we try dividing 13,192,535 by 3:
13,192,535 ÷ 3 = 4,397,511.6667
If the quotient is a whole number, then 3 and 4,397,511.6667 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 | 13,192,535 | |
| -1 | -13,192,535 |
Let's try dividing by 4:
13,192,535 ÷ 4 = 3,298,133.75
If the quotient is a whole number, then 4 and 3,298,133.75 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 | 13,192,535 | |
| -1 | 13,192,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 37 | 145 | 185 | 1,073 | 2,459 | 5,365 | 12,295 | 71,311 | 90,983 | 356,555 | 454,915 | 2,638,507 | 13,192,535 |
| -1 | -5 | -29 | -37 | -145 | -185 | -1,073 | -2,459 | -5,365 | -12,295 | -71,311 | -90,983 | -356,555 | -454,915 | -2,638,507 | -13,192,535 |
