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 12,070,409, 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 | 12,070,409 | |
| -1 | -12,070,409 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,070,409.
Example:
1 x 12,070,409 = 12,070,409
and
-1 x -12,070,409 = 12,070,409
Notice both answers equal 12,070,409
With that explanation out of the way, let's continue. Next, we take the number 12,070,409 and divide it by 2:
12,070,409 ÷ 2 = 6,035,204.5
If the quotient is a whole number, then 2 and 6,035,204.5 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 | 12,070,409 | |
| -1 | -12,070,409 |
Now, we try dividing 12,070,409 by 3:
12,070,409 ÷ 3 = 4,023,469.6667
If the quotient is a whole number, then 3 and 4,023,469.6667 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 | 12,070,409 | |
| -1 | -12,070,409 |
Let's try dividing by 4:
12,070,409 ÷ 4 = 3,017,602.25
If the quotient is a whole number, then 4 and 3,017,602.25 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 | 12,070,409 | |
| -1 | 12,070,409 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 101 | 317 | 377 | 1,313 | 2,929 | 4,121 | 9,193 | 32,017 | 38,077 | 119,509 | 416,221 | 928,493 | 12,070,409 |
| -1 | -13 | -29 | -101 | -317 | -377 | -1,313 | -2,929 | -4,121 | -9,193 | -32,017 | -38,077 | -119,509 | -416,221 | -928,493 | -12,070,409 |
