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 3,061,121, 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 | 3,061,121 | |
| -1 | -3,061,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,061,121.
Example:
1 x 3,061,121 = 3,061,121
and
-1 x -3,061,121 = 3,061,121
Notice both answers equal 3,061,121
With that explanation out of the way, let's continue. Next, we take the number 3,061,121 and divide it by 2:
3,061,121 ÷ 2 = 1,530,560.5
If the quotient is a whole number, then 2 and 1,530,560.5 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 | 3,061,121 | |
| -1 | -3,061,121 |
Now, we try dividing 3,061,121 by 3:
3,061,121 ÷ 3 = 1,020,373.6667
If the quotient is a whole number, then 3 and 1,020,373.6667 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 | 3,061,121 | |
| -1 | -3,061,121 |
Let's try dividing by 4:
3,061,121 ÷ 4 = 765,280.25
If the quotient is a whole number, then 4 and 765,280.25 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 | 3,061,121 | |
| -1 | 3,061,121 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 53 | 223 | 259 | 371 | 1,561 | 1,961 | 8,251 | 11,819 | 13,727 | 57,757 | 82,733 | 437,303 | 3,061,121 |
| -1 | -7 | -37 | -53 | -223 | -259 | -371 | -1,561 | -1,961 | -8,251 | -11,819 | -13,727 | -57,757 | -82,733 | -437,303 | -3,061,121 |
