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 46,888,421, 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 | 46,888,421 | |
| -1 | -46,888,421 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 46,888,421.
Example:
1 x 46,888,421 = 46,888,421
and
-1 x -46,888,421 = 46,888,421
Notice both answers equal 46,888,421
With that explanation out of the way, let's continue. Next, we take the number 46,888,421 and divide it by 2:
46,888,421 ÷ 2 = 23,444,210.5
If the quotient is a whole number, then 2 and 23,444,210.5 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 | 46,888,421 | |
| -1 | -46,888,421 |
Now, we try dividing 46,888,421 by 3:
46,888,421 ÷ 3 = 15,629,473.6667
If the quotient is a whole number, then 3 and 15,629,473.6667 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 | 46,888,421 | |
| -1 | -46,888,421 |
Let's try dividing by 4:
46,888,421 ÷ 4 = 11,722,105.25
If the quotient is a whole number, then 4 and 11,722,105.25 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 | 46,888,421 | |
| -1 | 46,888,421 |
If you did it right, you will end up with this table:
| 1 | 23 | 59 | 109 | 317 | 1,357 | 2,507 | 6,431 | 7,291 | 18,703 | 34,553 | 147,913 | 430,169 | 794,719 | 2,038,627 | 46,888,421 |
| -1 | -23 | -59 | -109 | -317 | -1,357 | -2,507 | -6,431 | -7,291 | -18,703 | -34,553 | -147,913 | -430,169 | -794,719 | -2,038,627 | -46,888,421 |
