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 14,406,145, 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 | 14,406,145 | |
| -1 | -14,406,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,406,145.
Example:
1 x 14,406,145 = 14,406,145
and
-1 x -14,406,145 = 14,406,145
Notice both answers equal 14,406,145
With that explanation out of the way, let's continue. Next, we take the number 14,406,145 and divide it by 2:
14,406,145 ÷ 2 = 7,203,072.5
If the quotient is a whole number, then 2 and 7,203,072.5 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 | 14,406,145 | |
| -1 | -14,406,145 |
Now, we try dividing 14,406,145 by 3:
14,406,145 ÷ 3 = 4,802,048.3333
If the quotient is a whole number, then 3 and 4,802,048.3333 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 | 14,406,145 | |
| -1 | -14,406,145 |
Let's try dividing by 4:
14,406,145 ÷ 4 = 3,601,536.25
If the quotient is a whole number, then 4 and 3,601,536.25 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 | 14,406,145 | |
| -1 | 14,406,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 251 | 883 | 1,255 | 3,263 | 4,415 | 11,479 | 16,315 | 57,395 | 221,633 | 1,108,165 | 2,881,229 | 14,406,145 |
| -1 | -5 | -13 | -65 | -251 | -883 | -1,255 | -3,263 | -4,415 | -11,479 | -16,315 | -57,395 | -221,633 | -1,108,165 | -2,881,229 | -14,406,145 |
