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 4,168,307, 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 | 4,168,307 | |
| -1 | -4,168,307 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,168,307.
Example:
1 x 4,168,307 = 4,168,307
and
-1 x -4,168,307 = 4,168,307
Notice both answers equal 4,168,307
With that explanation out of the way, let's continue. Next, we take the number 4,168,307 and divide it by 2:
4,168,307 ÷ 2 = 2,084,153.5
If the quotient is a whole number, then 2 and 2,084,153.5 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 | 4,168,307 | |
| -1 | -4,168,307 |
Now, we try dividing 4,168,307 by 3:
4,168,307 ÷ 3 = 1,389,435.6667
If the quotient is a whole number, then 3 and 1,389,435.6667 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 | 4,168,307 | |
| -1 | -4,168,307 |
Let's try dividing by 4:
4,168,307 ÷ 4 = 1,042,076.75
If the quotient is a whole number, then 4 and 1,042,076.75 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 | 4,168,307 | |
| -1 | 4,168,307 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 103 | 143 | 283 | 1,133 | 1,339 | 3,113 | 3,679 | 14,729 | 29,149 | 40,469 | 320,639 | 378,937 | 4,168,307 |
| -1 | -11 | -13 | -103 | -143 | -283 | -1,133 | -1,339 | -3,113 | -3,679 | -14,729 | -29,149 | -40,469 | -320,639 | -378,937 | -4,168,307 |
