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 3,447,145, 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 | 3,447,145 | |
| -1 | -3,447,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,447,145.
Example:
1 x 3,447,145 = 3,447,145
and
-1 x -3,447,145 = 3,447,145
Notice both answers equal 3,447,145
With that explanation out of the way, let's continue. Next, we take the number 3,447,145 and divide it by 2:
3,447,145 ÷ 2 = 1,723,572.5
If the quotient is a whole number, then 2 and 1,723,572.5 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 | 3,447,145 | |
| -1 | -3,447,145 |
Now, we try dividing 3,447,145 by 3:
3,447,145 ÷ 3 = 1,149,048.3333
If the quotient is a whole number, then 3 and 1,149,048.3333 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 | 3,447,145 | |
| -1 | -3,447,145 |
Let's try dividing by 4:
3,447,145 ÷ 4 = 861,786.25
If the quotient is a whole number, then 4 and 861,786.25 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 | 3,447,145 | |
| -1 | 3,447,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 181 | 293 | 905 | 1,465 | 2,353 | 3,809 | 11,765 | 19,045 | 53,033 | 265,165 | 689,429 | 3,447,145 |
| -1 | -5 | -13 | -65 | -181 | -293 | -905 | -1,465 | -2,353 | -3,809 | -11,765 | -19,045 | -53,033 | -265,165 | -689,429 | -3,447,145 |
