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 45,637,115, 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 | 45,637,115 | |
| -1 | -45,637,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,637,115.
Example:
1 x 45,637,115 = 45,637,115
and
-1 x -45,637,115 = 45,637,115
Notice both answers equal 45,637,115
With that explanation out of the way, let's continue. Next, we take the number 45,637,115 and divide it by 2:
45,637,115 ÷ 2 = 22,818,557.5
If the quotient is a whole number, then 2 and 22,818,557.5 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 | 45,637,115 | |
| -1 | -45,637,115 |
Now, we try dividing 45,637,115 by 3:
45,637,115 ÷ 3 = 15,212,371.6667
If the quotient is a whole number, then 3 and 15,212,371.6667 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 | 45,637,115 | |
| -1 | -45,637,115 |
Let's try dividing by 4:
45,637,115 ÷ 4 = 11,409,278.75
If the quotient is a whole number, then 4 and 11,409,278.75 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 | 45,637,115 | |
| -1 | 45,637,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 79 | 155 | 395 | 2,449 | 3,727 | 12,245 | 18,635 | 115,537 | 294,433 | 577,685 | 1,472,165 | 9,127,423 | 45,637,115 |
| -1 | -5 | -31 | -79 | -155 | -395 | -2,449 | -3,727 | -12,245 | -18,635 | -115,537 | -294,433 | -577,685 | -1,472,165 | -9,127,423 | -45,637,115 |
