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 30,453,449, 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 | 30,453,449 | |
| -1 | -30,453,449 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,453,449.
Example:
1 x 30,453,449 = 30,453,449
and
-1 x -30,453,449 = 30,453,449
Notice both answers equal 30,453,449
With that explanation out of the way, let's continue. Next, we take the number 30,453,449 and divide it by 2:
30,453,449 ÷ 2 = 15,226,724.5
If the quotient is a whole number, then 2 and 15,226,724.5 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 | 30,453,449 | |
| -1 | -30,453,449 |
Now, we try dividing 30,453,449 by 3:
30,453,449 ÷ 3 = 10,151,149.6667
If the quotient is a whole number, then 3 and 10,151,149.6667 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 | 30,453,449 | |
| -1 | -30,453,449 |
Let's try dividing by 4:
30,453,449 ÷ 4 = 7,613,362.25
If the quotient is a whole number, then 4 and 7,613,362.25 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 | 30,453,449 | |
| -1 | 30,453,449 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 179 | 299 | 569 | 2,327 | 4,117 | 7,397 | 13,087 | 53,521 | 101,851 | 170,131 | 1,324,063 | 2,342,573 | 30,453,449 |
| -1 | -13 | -23 | -179 | -299 | -569 | -2,327 | -4,117 | -7,397 | -13,087 | -53,521 | -101,851 | -170,131 | -1,324,063 | -2,342,573 | -30,453,449 |
