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 14,305,225, 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 | 14,305,225 | |
| -1 | -14,305,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,305,225.
Example:
1 x 14,305,225 = 14,305,225
and
-1 x -14,305,225 = 14,305,225
Notice both answers equal 14,305,225
With that explanation out of the way, let's continue. Next, we take the number 14,305,225 and divide it by 2:
14,305,225 ÷ 2 = 7,152,612.5
If the quotient is a whole number, then 2 and 7,152,612.5 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 | 14,305,225 | |
| -1 | -14,305,225 |
Now, we try dividing 14,305,225 by 3:
14,305,225 ÷ 3 = 4,768,408.3333
If the quotient is a whole number, then 3 and 4,768,408.3333 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 | 14,305,225 | |
| -1 | -14,305,225 |
Let's try dividing by 4:
14,305,225 ÷ 4 = 3,576,306.25
If the quotient is a whole number, then 4 and 3,576,306.25 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 | 14,305,225 | |
| -1 | 14,305,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 121 | 275 | 605 | 3,025 | 4,729 | 23,645 | 52,019 | 118,225 | 260,095 | 572,209 | 1,300,475 | 2,861,045 | 14,305,225 |
| -1 | -5 | -11 | -25 | -55 | -121 | -275 | -605 | -3,025 | -4,729 | -23,645 | -52,019 | -118,225 | -260,095 | -572,209 | -1,300,475 | -2,861,045 | -14,305,225 |
