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 45,015,655, 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 | 45,015,655 | |
| -1 | -45,015,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,015,655.
Example:
1 x 45,015,655 = 45,015,655
and
-1 x -45,015,655 = 45,015,655
Notice both answers equal 45,015,655
With that explanation out of the way, let's continue. Next, we take the number 45,015,655 and divide it by 2:
45,015,655 ÷ 2 = 22,507,827.5
If the quotient is a whole number, then 2 and 22,507,827.5 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 | 45,015,655 | |
| -1 | -45,015,655 |
Now, we try dividing 45,015,655 by 3:
45,015,655 ÷ 3 = 15,005,218.3333
If the quotient is a whole number, then 3 and 15,005,218.3333 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 | 45,015,655 | |
| -1 | -45,015,655 |
Let's try dividing by 4:
45,015,655 ÷ 4 = 11,253,913.75
If the quotient is a whole number, then 4 and 11,253,913.75 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 | 45,015,655 | |
| -1 | 45,015,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 613 | 773 | 3,065 | 3,865 | 11,647 | 14,687 | 58,235 | 73,435 | 473,849 | 2,369,245 | 9,003,131 | 45,015,655 |
| -1 | -5 | -19 | -95 | -613 | -773 | -3,065 | -3,865 | -11,647 | -14,687 | -58,235 | -73,435 | -473,849 | -2,369,245 | -9,003,131 | -45,015,655 |
