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 48,888,581, 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 | 48,888,581 | |
| -1 | -48,888,581 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 48,888,581.
Example:
1 x 48,888,581 = 48,888,581
and
-1 x -48,888,581 = 48,888,581
Notice both answers equal 48,888,581
With that explanation out of the way, let's continue. Next, we take the number 48,888,581 and divide it by 2:
48,888,581 ÷ 2 = 24,444,290.5
If the quotient is a whole number, then 2 and 24,444,290.5 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 | 48,888,581 | |
| -1 | -48,888,581 |
Now, we try dividing 48,888,581 by 3:
48,888,581 ÷ 3 = 16,296,193.6667
If the quotient is a whole number, then 3 and 16,296,193.6667 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 | 48,888,581 | |
| -1 | -48,888,581 |
Let's try dividing by 4:
48,888,581 ÷ 4 = 12,222,145.25
If the quotient is a whole number, then 4 and 12,222,145.25 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 | 48,888,581 | |
| -1 | 48,888,581 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 37 | 217 | 259 | 1,147 | 6,089 | 8,029 | 42,623 | 188,759 | 225,293 | 1,321,313 | 1,577,051 | 6,984,083 | 48,888,581 |
| -1 | -7 | -31 | -37 | -217 | -259 | -1,147 | -6,089 | -8,029 | -42,623 | -188,759 | -225,293 | -1,321,313 | -1,577,051 | -6,984,083 | -48,888,581 |
