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 3,347,249, 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 | 3,347,249 | |
| -1 | -3,347,249 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,347,249.
Example:
1 x 3,347,249 = 3,347,249
and
-1 x -3,347,249 = 3,347,249
Notice both answers equal 3,347,249
With that explanation out of the way, let's continue. Next, we take the number 3,347,249 and divide it by 2:
3,347,249 ÷ 2 = 1,673,624.5
If the quotient is a whole number, then 2 and 1,673,624.5 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 | 3,347,249 | |
| -1 | -3,347,249 |
Now, we try dividing 3,347,249 by 3:
3,347,249 ÷ 3 = 1,115,749.6667
If the quotient is a whole number, then 3 and 1,115,749.6667 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 | 3,347,249 | |
| -1 | -3,347,249 |
Let's try dividing by 4:
3,347,249 ÷ 4 = 836,812.25
If the quotient is a whole number, then 4 and 836,812.25 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 | 3,347,249 | |
| -1 | 3,347,249 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 43 | 241 | 323 | 731 | 817 | 4,097 | 4,579 | 10,363 | 13,889 | 77,843 | 176,171 | 196,897 | 3,347,249 |
| -1 | -17 | -19 | -43 | -241 | -323 | -731 | -817 | -4,097 | -4,579 | -10,363 | -13,889 | -77,843 | -176,171 | -196,897 | -3,347,249 |
