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 13,254,409, 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 | 13,254,409 | |
| -1 | -13,254,409 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,254,409.
Example:
1 x 13,254,409 = 13,254,409
and
-1 x -13,254,409 = 13,254,409
Notice both answers equal 13,254,409
With that explanation out of the way, let's continue. Next, we take the number 13,254,409 and divide it by 2:
13,254,409 ÷ 2 = 6,627,204.5
If the quotient is a whole number, then 2 and 6,627,204.5 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 | 13,254,409 | |
| -1 | -13,254,409 |
Now, we try dividing 13,254,409 by 3:
13,254,409 ÷ 3 = 4,418,136.3333
If the quotient is a whole number, then 3 and 4,418,136.3333 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 | 13,254,409 | |
| -1 | -13,254,409 |
Let's try dividing by 4:
13,254,409 ÷ 4 = 3,313,602.25
If the quotient is a whole number, then 4 and 3,313,602.25 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 | 13,254,409 | |
| -1 | 13,254,409 |
If you did it right, you will end up with this table:
| 1 | 7 | 59 | 67 | 413 | 469 | 479 | 3,353 | 3,953 | 27,671 | 28,261 | 32,093 | 197,827 | 224,651 | 1,893,487 | 13,254,409 |
| -1 | -7 | -59 | -67 | -413 | -469 | -479 | -3,353 | -3,953 | -27,671 | -28,261 | -32,093 | -197,827 | -224,651 | -1,893,487 | -13,254,409 |
