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 3,475,447, 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 | 3,475,447 | |
| -1 | -3,475,447 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,475,447.
Example:
1 x 3,475,447 = 3,475,447
and
-1 x -3,475,447 = 3,475,447
Notice both answers equal 3,475,447
With that explanation out of the way, let's continue. Next, we take the number 3,475,447 and divide it by 2:
3,475,447 ÷ 2 = 1,737,723.5
If the quotient is a whole number, then 2 and 1,737,723.5 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 | 3,475,447 | |
| -1 | -3,475,447 |
Now, we try dividing 3,475,447 by 3:
3,475,447 ÷ 3 = 1,158,482.3333
If the quotient is a whole number, then 3 and 1,158,482.3333 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 | 3,475,447 | |
| -1 | -3,475,447 |
Let's try dividing by 4:
3,475,447 ÷ 4 = 868,861.75
If the quotient is a whole number, then 4 and 868,861.75 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 | 3,475,447 | |
| -1 | 3,475,447 |
If you did it right, you will end up with this table:
| 1 | 29 | 37 | 41 | 79 | 1,073 | 1,189 | 1,517 | 2,291 | 2,923 | 3,239 | 43,993 | 84,767 | 93,931 | 119,843 | 3,475,447 |
| -1 | -29 | -37 | -41 | -79 | -1,073 | -1,189 | -1,517 | -2,291 | -2,923 | -3,239 | -43,993 | -84,767 | -93,931 | -119,843 | -3,475,447 |
