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 45,173,843, 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 | 45,173,843 | |
| -1 | -45,173,843 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,173,843.
Example:
1 x 45,173,843 = 45,173,843
and
-1 x -45,173,843 = 45,173,843
Notice both answers equal 45,173,843
With that explanation out of the way, let's continue. Next, we take the number 45,173,843 and divide it by 2:
45,173,843 ÷ 2 = 22,586,921.5
If the quotient is a whole number, then 2 and 22,586,921.5 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 | 45,173,843 | |
| -1 | -45,173,843 |
Now, we try dividing 45,173,843 by 3:
45,173,843 ÷ 3 = 15,057,947.6667
If the quotient is a whole number, then 3 and 15,057,947.6667 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 | 45,173,843 | |
| -1 | -45,173,843 |
Let's try dividing by 4:
45,173,843 ÷ 4 = 11,293,460.75
If the quotient is a whole number, then 4 and 11,293,460.75 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 | 45,173,843 | |
| -1 | 45,173,843 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 103 | 143 | 1,133 | 1,339 | 3,067 | 14,729 | 33,737 | 39,871 | 315,901 | 438,581 | 3,474,911 | 4,106,713 | 45,173,843 |
| -1 | -11 | -13 | -103 | -143 | -1,133 | -1,339 | -3,067 | -14,729 | -33,737 | -39,871 | -315,901 | -438,581 | -3,474,911 | -4,106,713 | -45,173,843 |
