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 14,520,545, 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 | 14,520,545 | |
| -1 | -14,520,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,520,545.
Example:
1 x 14,520,545 = 14,520,545
and
-1 x -14,520,545 = 14,520,545
Notice both answers equal 14,520,545
With that explanation out of the way, let's continue. Next, we take the number 14,520,545 and divide it by 2:
14,520,545 ÷ 2 = 7,260,272.5
If the quotient is a whole number, then 2 and 7,260,272.5 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 | 14,520,545 | |
| -1 | -14,520,545 |
Now, we try dividing 14,520,545 by 3:
14,520,545 ÷ 3 = 4,840,181.6667
If the quotient is a whole number, then 3 and 4,840,181.6667 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 | 14,520,545 | |
| -1 | -14,520,545 |
Let's try dividing by 4:
14,520,545 ÷ 4 = 3,630,136.25
If the quotient is a whole number, then 4 and 3,630,136.25 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 | 14,520,545 | |
| -1 | 14,520,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 127 | 635 | 1,651 | 1,759 | 8,255 | 8,795 | 22,867 | 114,335 | 223,393 | 1,116,965 | 2,904,109 | 14,520,545 |
| -1 | -5 | -13 | -65 | -127 | -635 | -1,651 | -1,759 | -8,255 | -8,795 | -22,867 | -114,335 | -223,393 | -1,116,965 | -2,904,109 | -14,520,545 |
