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 46,040,813, 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 | 46,040,813 | |
| -1 | -46,040,813 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 46,040,813.
Example:
1 x 46,040,813 = 46,040,813
and
-1 x -46,040,813 = 46,040,813
Notice both answers equal 46,040,813
With that explanation out of the way, let's continue. Next, we take the number 46,040,813 and divide it by 2:
46,040,813 ÷ 2 = 23,020,406.5
If the quotient is a whole number, then 2 and 23,020,406.5 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 | 46,040,813 | |
| -1 | -46,040,813 |
Now, we try dividing 46,040,813 by 3:
46,040,813 ÷ 3 = 15,346,937.6667
If the quotient is a whole number, then 3 and 15,346,937.6667 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 | 46,040,813 | |
| -1 | -46,040,813 |
Let's try dividing by 4:
46,040,813 ÷ 4 = 11,510,203.25
If the quotient is a whole number, then 4 and 11,510,203.25 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 | 46,040,813 | |
| -1 | 46,040,813 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 383 | 1,321 | 2,681 | 4,979 | 9,247 | 17,173 | 34,853 | 120,211 | 505,943 | 3,541,601 | 6,577,259 | 46,040,813 |
| -1 | -7 | -13 | -91 | -383 | -1,321 | -2,681 | -4,979 | -9,247 | -17,173 | -34,853 | -120,211 | -505,943 | -3,541,601 | -6,577,259 | -46,040,813 |
