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 45,051,413, 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 | 45,051,413 | |
| -1 | -45,051,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,051,413.
Example:
1 x 45,051,413 = 45,051,413
and
-1 x -45,051,413 = 45,051,413
Notice both answers equal 45,051,413
With that explanation out of the way, let's continue. Next, we take the number 45,051,413 and divide it by 2:
45,051,413 ÷ 2 = 22,525,706.5
If the quotient is a whole number, then 2 and 22,525,706.5 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 | 45,051,413 | |
| -1 | -45,051,413 |
Now, we try dividing 45,051,413 by 3:
45,051,413 ÷ 3 = 15,017,137.6667
If the quotient is a whole number, then 3 and 15,017,137.6667 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 | 45,051,413 | |
| -1 | -45,051,413 |
Let's try dividing by 4:
45,051,413 ÷ 4 = 11,262,853.25
If the quotient is a whole number, then 4 and 11,262,853.25 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 | 45,051,413 | |
| -1 | 45,051,413 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 29 | 209 | 319 | 551 | 6,061 | 7,433 | 81,763 | 141,227 | 215,557 | 1,553,497 | 2,371,127 | 4,095,583 | 45,051,413 |
| -1 | -11 | -19 | -29 | -209 | -319 | -551 | -6,061 | -7,433 | -81,763 | -141,227 | -215,557 | -1,553,497 | -2,371,127 | -4,095,583 | -45,051,413 |
