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 12,828,067, 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 | 12,828,067 | |
| -1 | -12,828,067 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,828,067.
Example:
1 x 12,828,067 = 12,828,067
and
-1 x -12,828,067 = 12,828,067
Notice both answers equal 12,828,067
With that explanation out of the way, let's continue. Next, we take the number 12,828,067 and divide it by 2:
12,828,067 ÷ 2 = 6,414,033.5
If the quotient is a whole number, then 2 and 6,414,033.5 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 | 12,828,067 | |
| -1 | -12,828,067 |
Now, we try dividing 12,828,067 by 3:
12,828,067 ÷ 3 = 4,276,022.3333
If the quotient is a whole number, then 3 and 4,276,022.3333 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 | 12,828,067 | |
| -1 | -12,828,067 |
Let's try dividing by 4:
12,828,067 ÷ 4 = 3,207,016.75
If the quotient is a whole number, then 4 and 3,207,016.75 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 | 12,828,067 | |
| -1 | 12,828,067 |
If you did it right, you will end up with this table:
| 1 | 7 | 53 | 71 | 371 | 487 | 497 | 3,409 | 3,763 | 25,811 | 26,341 | 34,577 | 180,677 | 242,039 | 1,832,581 | 12,828,067 |
| -1 | -7 | -53 | -71 | -371 | -487 | -497 | -3,409 | -3,763 | -25,811 | -26,341 | -34,577 | -180,677 | -242,039 | -1,832,581 | -12,828,067 |
