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 13,241,545, 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 | 13,241,545 | |
| -1 | -13,241,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,241,545.
Example:
1 x 13,241,545 = 13,241,545
and
-1 x -13,241,545 = 13,241,545
Notice both answers equal 13,241,545
With that explanation out of the way, let's continue. Next, we take the number 13,241,545 and divide it by 2:
13,241,545 ÷ 2 = 6,620,772.5
If the quotient is a whole number, then 2 and 6,620,772.5 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 | 13,241,545 | |
| -1 | -13,241,545 |
Now, we try dividing 13,241,545 by 3:
13,241,545 ÷ 3 = 4,413,848.3333
If the quotient is a whole number, then 3 and 4,413,848.3333 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 | 13,241,545 | |
| -1 | -13,241,545 |
Let's try dividing by 4:
13,241,545 ÷ 4 = 3,310,386.25
If the quotient is a whole number, then 4 and 3,310,386.25 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 | 13,241,545 | |
| -1 | 13,241,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 47 | 67 | 145 | 235 | 335 | 841 | 1,363 | 1,943 | 3,149 | 4,205 | 6,815 | 9,715 | 15,745 | 39,527 | 56,347 | 91,321 | 197,635 | 281,735 | 456,605 | 2,648,309 | 13,241,545 |
| -1 | -5 | -29 | -47 | -67 | -145 | -235 | -335 | -841 | -1,363 | -1,943 | -3,149 | -4,205 | -6,815 | -9,715 | -15,745 | -39,527 | -56,347 | -91,321 | -197,635 | -281,735 | -456,605 | -2,648,309 | -13,241,545 |
