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 3,151,253, 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 | 3,151,253 | |
| -1 | -3,151,253 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,151,253.
Example:
1 x 3,151,253 = 3,151,253
and
-1 x -3,151,253 = 3,151,253
Notice both answers equal 3,151,253
With that explanation out of the way, let's continue. Next, we take the number 3,151,253 and divide it by 2:
3,151,253 ÷ 2 = 1,575,626.5
If the quotient is a whole number, then 2 and 1,575,626.5 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 | 3,151,253 | |
| -1 | -3,151,253 |
Now, we try dividing 3,151,253 by 3:
3,151,253 ÷ 3 = 1,050,417.6667
If the quotient is a whole number, then 3 and 1,050,417.6667 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 | 3,151,253 | |
| -1 | -3,151,253 |
Let's try dividing by 4:
3,151,253 ÷ 4 = 787,813.25
If the quotient is a whole number, then 4 and 787,813.25 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 | 3,151,253 | |
| -1 | 3,151,253 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 37 | 161 | 259 | 529 | 851 | 3,703 | 5,957 | 12,167 | 19,573 | 85,169 | 137,011 | 450,179 | 3,151,253 |
| -1 | -7 | -23 | -37 | -161 | -259 | -529 | -851 | -3,703 | -5,957 | -12,167 | -19,573 | -85,169 | -137,011 | -450,179 | -3,151,253 |
