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 14,160,545, 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 | 14,160,545 | |
| -1 | -14,160,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,160,545.
Example:
1 x 14,160,545 = 14,160,545
and
-1 x -14,160,545 = 14,160,545
Notice both answers equal 14,160,545
With that explanation out of the way, let's continue. Next, we take the number 14,160,545 and divide it by 2:
14,160,545 ÷ 2 = 7,080,272.5
If the quotient is a whole number, then 2 and 7,080,272.5 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 | 14,160,545 | |
| -1 | -14,160,545 |
Now, we try dividing 14,160,545 by 3:
14,160,545 ÷ 3 = 4,720,181.6667
If the quotient is a whole number, then 3 and 4,720,181.6667 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 | 14,160,545 | |
| -1 | -14,160,545 |
Let's try dividing by 4:
14,160,545 ÷ 4 = 3,540,136.25
If the quotient is a whole number, then 4 and 3,540,136.25 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 | 14,160,545 | |
| -1 | 14,160,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 43 | 97 | 215 | 301 | 485 | 679 | 1,505 | 3,395 | 4,171 | 9,409 | 20,855 | 29,197 | 47,045 | 65,863 | 145,985 | 329,315 | 404,587 | 2,022,935 | 2,832,109 | 14,160,545 |
| -1 | -5 | -7 | -35 | -43 | -97 | -215 | -301 | -485 | -679 | -1,505 | -3,395 | -4,171 | -9,409 | -20,855 | -29,197 | -47,045 | -65,863 | -145,985 | -329,315 | -404,587 | -2,022,935 | -2,832,109 | -14,160,545 |
