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 5,545,397, 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 | 5,545,397 | |
| -1 | -5,545,397 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,545,397.
Example:
1 x 5,545,397 = 5,545,397
and
-1 x -5,545,397 = 5,545,397
Notice both answers equal 5,545,397
With that explanation out of the way, let's continue. Next, we take the number 5,545,397 and divide it by 2:
5,545,397 ÷ 2 = 2,772,698.5
If the quotient is a whole number, then 2 and 2,772,698.5 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 | 5,545,397 | |
| -1 | -5,545,397 |
Now, we try dividing 5,545,397 by 3:
5,545,397 ÷ 3 = 1,848,465.6667
If the quotient is a whole number, then 3 and 1,848,465.6667 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 | 5,545,397 | |
| -1 | -5,545,397 |
Let's try dividing by 4:
5,545,397 ÷ 4 = 1,386,349.25
If the quotient is a whole number, then 4 and 1,386,349.25 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 | 5,545,397 | |
| -1 | 5,545,397 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 19 | 143 | 157 | 169 | 209 | 247 | 1,727 | 1,859 | 2,041 | 2,717 | 2,983 | 3,211 | 22,451 | 26,533 | 32,813 | 35,321 | 38,779 | 291,863 | 426,569 | 504,127 | 5,545,397 |
| -1 | -11 | -13 | -19 | -143 | -157 | -169 | -209 | -247 | -1,727 | -1,859 | -2,041 | -2,717 | -2,983 | -3,211 | -22,451 | -26,533 | -32,813 | -35,321 | -38,779 | -291,863 | -426,569 | -504,127 | -5,545,397 |
