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 10,042,207, 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 | 10,042,207 | |
| -1 | -10,042,207 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,042,207.
Example:
1 x 10,042,207 = 10,042,207
and
-1 x -10,042,207 = 10,042,207
Notice both answers equal 10,042,207
With that explanation out of the way, let's continue. Next, we take the number 10,042,207 and divide it by 2:
10,042,207 ÷ 2 = 5,021,103.5
If the quotient is a whole number, then 2 and 5,021,103.5 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 | 10,042,207 | |
| -1 | -10,042,207 |
Now, we try dividing 10,042,207 by 3:
10,042,207 ÷ 3 = 3,347,402.3333
If the quotient is a whole number, then 3 and 3,347,402.3333 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 | 10,042,207 | |
| -1 | -10,042,207 |
Let's try dividing by 4:
10,042,207 ÷ 4 = 2,510,551.75
If the quotient is a whole number, then 4 and 2,510,551.75 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 | 10,042,207 | |
| -1 | 10,042,207 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 37 | 49 | 191 | 203 | 259 | 1,073 | 1,337 | 1,421 | 1,813 | 5,539 | 7,067 | 7,511 | 9,359 | 38,773 | 49,469 | 52,577 | 204,943 | 271,411 | 346,283 | 1,434,601 | 10,042,207 |
| -1 | -7 | -29 | -37 | -49 | -191 | -203 | -259 | -1,073 | -1,337 | -1,421 | -1,813 | -5,539 | -7,067 | -7,511 | -9,359 | -38,773 | -49,469 | -52,577 | -204,943 | -271,411 | -346,283 | -1,434,601 | -10,042,207 |
