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 1,447,355, 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 | 1,447,355 | |
| -1 | -1,447,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,447,355.
Example:
1 x 1,447,355 = 1,447,355
and
-1 x -1,447,355 = 1,447,355
Notice both answers equal 1,447,355
With that explanation out of the way, let's continue. Next, we take the number 1,447,355 and divide it by 2:
1,447,355 ÷ 2 = 723,677.5
If the quotient is a whole number, then 2 and 723,677.5 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 | 1,447,355 | |
| -1 | -1,447,355 |
Now, we try dividing 1,447,355 by 3:
1,447,355 ÷ 3 = 482,451.6667
If the quotient is a whole number, then 3 and 482,451.6667 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 | 1,447,355 | |
| -1 | -1,447,355 |
Let's try dividing by 4:
1,447,355 ÷ 4 = 361,838.75
If the quotient is a whole number, then 4 and 361,838.75 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 | 1,447,355 | |
| -1 | 1,447,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 3,181 | 15,905 | 22,267 | 41,353 | 111,335 | 206,765 | 289,471 | 1,447,355 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -3,181 | -15,905 | -22,267 | -41,353 | -111,335 | -206,765 | -289,471 | -1,447,355 |
