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 12,413,023, 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 | 12,413,023 | |
| -1 | -12,413,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,413,023.
Example:
1 x 12,413,023 = 12,413,023
and
-1 x -12,413,023 = 12,413,023
Notice both answers equal 12,413,023
With that explanation out of the way, let's continue. Next, we take the number 12,413,023 and divide it by 2:
12,413,023 ÷ 2 = 6,206,511.5
If the quotient is a whole number, then 2 and 6,206,511.5 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 | 12,413,023 | |
| -1 | -12,413,023 |
Now, we try dividing 12,413,023 by 3:
12,413,023 ÷ 3 = 4,137,674.3333
If the quotient is a whole number, then 3 and 4,137,674.3333 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 | 12,413,023 | |
| -1 | -12,413,023 |
Let's try dividing by 4:
12,413,023 ÷ 4 = 3,103,255.75
If the quotient is a whole number, then 4 and 3,103,255.75 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 | 12,413,023 | |
| -1 | 12,413,023 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 49 | 67 | 133 | 199 | 469 | 931 | 1,273 | 1,393 | 3,283 | 3,781 | 8,911 | 9,751 | 13,333 | 26,467 | 62,377 | 93,331 | 185,269 | 253,327 | 653,317 | 1,773,289 | 12,413,023 |
| -1 | -7 | -19 | -49 | -67 | -133 | -199 | -469 | -931 | -1,273 | -1,393 | -3,283 | -3,781 | -8,911 | -9,751 | -13,333 | -26,467 | -62,377 | -93,331 | -185,269 | -253,327 | -653,317 | -1,773,289 | -12,413,023 |
