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 2,002,429, 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 | 2,002,429 | |
| -1 | -2,002,429 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,002,429.
Example:
1 x 2,002,429 = 2,002,429
and
-1 x -2,002,429 = 2,002,429
Notice both answers equal 2,002,429
With that explanation out of the way, let's continue. Next, we take the number 2,002,429 and divide it by 2:
2,002,429 ÷ 2 = 1,001,214.5
If the quotient is a whole number, then 2 and 1,001,214.5 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 | 2,002,429 | |
| -1 | -2,002,429 |
Now, we try dividing 2,002,429 by 3:
2,002,429 ÷ 3 = 667,476.3333
If the quotient is a whole number, then 3 and 667,476.3333 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 | 2,002,429 | |
| -1 | -2,002,429 |
Let's try dividing by 4:
2,002,429 ÷ 4 = 500,607.25
If the quotient is a whole number, then 4 and 500,607.25 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 | 2,002,429 | |
| -1 | 2,002,429 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 19 | 67 | 121 | 143 | 209 | 247 | 737 | 871 | 1,273 | 1,573 | 2,299 | 2,717 | 8,107 | 9,581 | 14,003 | 16,549 | 29,887 | 105,391 | 154,033 | 182,039 | 2,002,429 |
| -1 | -11 | -13 | -19 | -67 | -121 | -143 | -209 | -247 | -737 | -871 | -1,273 | -1,573 | -2,299 | -2,717 | -8,107 | -9,581 | -14,003 | -16,549 | -29,887 | -105,391 | -154,033 | -182,039 | -2,002,429 |
