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 4,511,171, 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 | 4,511,171 | |
| -1 | -4,511,171 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,511,171.
Example:
1 x 4,511,171 = 4,511,171
and
-1 x -4,511,171 = 4,511,171
Notice both answers equal 4,511,171
With that explanation out of the way, let's continue. Next, we take the number 4,511,171 and divide it by 2:
4,511,171 ÷ 2 = 2,255,585.5
If the quotient is a whole number, then 2 and 2,255,585.5 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 | 4,511,171 | |
| -1 | -4,511,171 |
Now, we try dividing 4,511,171 by 3:
4,511,171 ÷ 3 = 1,503,723.6667
If the quotient is a whole number, then 3 and 1,503,723.6667 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 | 4,511,171 | |
| -1 | -4,511,171 |
Let's try dividing by 4:
4,511,171 ÷ 4 = 1,127,792.75
If the quotient is a whole number, then 4 and 1,127,792.75 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 | 4,511,171 | |
| -1 | 4,511,171 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 167 | 227 | 1,169 | 1,589 | 2,839 | 3,859 | 19,873 | 27,013 | 37,909 | 265,363 | 644,453 | 4,511,171 |
| -1 | -7 | -17 | -119 | -167 | -227 | -1,169 | -1,589 | -2,839 | -3,859 | -19,873 | -27,013 | -37,909 | -265,363 | -644,453 | -4,511,171 |
