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 46,491,815, 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 | 46,491,815 | |
| -1 | -46,491,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 46,491,815.
Example:
1 x 46,491,815 = 46,491,815
and
-1 x -46,491,815 = 46,491,815
Notice both answers equal 46,491,815
With that explanation out of the way, let's continue. Next, we take the number 46,491,815 and divide it by 2:
46,491,815 ÷ 2 = 23,245,907.5
If the quotient is a whole number, then 2 and 23,245,907.5 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 | 46,491,815 | |
| -1 | -46,491,815 |
Now, we try dividing 46,491,815 by 3:
46,491,815 ÷ 3 = 15,497,271.6667
If the quotient is a whole number, then 3 and 15,497,271.6667 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 | 46,491,815 | |
| -1 | -46,491,815 |
Let's try dividing by 4:
46,491,815 ÷ 4 = 11,622,953.75
If the quotient is a whole number, then 4 and 11,622,953.75 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 | 46,491,815 | |
| -1 | 46,491,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 101 | 215 | 505 | 2,141 | 4,343 | 10,705 | 21,715 | 92,063 | 216,241 | 460,315 | 1,081,205 | 9,298,363 | 46,491,815 |
| -1 | -5 | -43 | -101 | -215 | -505 | -2,141 | -4,343 | -10,705 | -21,715 | -92,063 | -216,241 | -460,315 | -1,081,205 | -9,298,363 | -46,491,815 |
