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 4,131,347, 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 | 4,131,347 | |
| -1 | -4,131,347 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,131,347.
Example:
1 x 4,131,347 = 4,131,347
and
-1 x -4,131,347 = 4,131,347
Notice both answers equal 4,131,347
With that explanation out of the way, let's continue. Next, we take the number 4,131,347 and divide it by 2:
4,131,347 ÷ 2 = 2,065,673.5
If the quotient is a whole number, then 2 and 2,065,673.5 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 | 4,131,347 | |
| -1 | -4,131,347 |
Now, we try dividing 4,131,347 by 3:
4,131,347 ÷ 3 = 1,377,115.6667
If the quotient is a whole number, then 3 and 1,377,115.6667 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 | 4,131,347 | |
| -1 | -4,131,347 |
Let's try dividing by 4:
4,131,347 ÷ 4 = 1,032,836.75
If the quotient is a whole number, then 4 and 1,032,836.75 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 | 4,131,347 | |
| -1 | 4,131,347 |
If you did it right, you will end up with this table:
| 1 | 11 | 47 | 61 | 131 | 517 | 671 | 1,441 | 2,867 | 6,157 | 7,991 | 31,537 | 67,727 | 87,901 | 375,577 | 4,131,347 |
| -1 | -11 | -47 | -61 | -131 | -517 | -671 | -1,441 | -2,867 | -6,157 | -7,991 | -31,537 | -67,727 | -87,901 | -375,577 | -4,131,347 |
