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 10,412,143, 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 | 10,412,143 | |
| -1 | -10,412,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,412,143.
Example:
1 x 10,412,143 = 10,412,143
and
-1 x -10,412,143 = 10,412,143
Notice both answers equal 10,412,143
With that explanation out of the way, let's continue. Next, we take the number 10,412,143 and divide it by 2:
10,412,143 ÷ 2 = 5,206,071.5
If the quotient is a whole number, then 2 and 5,206,071.5 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 | 10,412,143 | |
| -1 | -10,412,143 |
Now, we try dividing 10,412,143 by 3:
10,412,143 ÷ 3 = 3,470,714.3333
If the quotient is a whole number, then 3 and 3,470,714.3333 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 | 10,412,143 | |
| -1 | -10,412,143 |
Let's try dividing by 4:
10,412,143 ÷ 4 = 2,603,035.75
If the quotient is a whole number, then 4 and 2,603,035.75 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 | 10,412,143 | |
| -1 | 10,412,143 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 59 | 119 | 413 | 1,003 | 1,483 | 7,021 | 10,381 | 25,211 | 87,497 | 176,477 | 612,479 | 1,487,449 | 10,412,143 |
| -1 | -7 | -17 | -59 | -119 | -413 | -1,003 | -1,483 | -7,021 | -10,381 | -25,211 | -87,497 | -176,477 | -612,479 | -1,487,449 | -10,412,143 |
