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 48,581,681, 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 | 48,581,681 | |
| -1 | -48,581,681 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 48,581,681.
Example:
1 x 48,581,681 = 48,581,681
and
-1 x -48,581,681 = 48,581,681
Notice both answers equal 48,581,681
With that explanation out of the way, let's continue. Next, we take the number 48,581,681 and divide it by 2:
48,581,681 ÷ 2 = 24,290,840.5
If the quotient is a whole number, then 2 and 24,290,840.5 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 | 48,581,681 | |
| -1 | -48,581,681 |
Now, we try dividing 48,581,681 by 3:
48,581,681 ÷ 3 = 16,193,893.6667
If the quotient is a whole number, then 3 and 16,193,893.6667 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 | 48,581,681 | |
| -1 | -48,581,681 |
Let's try dividing by 4:
48,581,681 ÷ 4 = 12,145,420.25
If the quotient is a whole number, then 4 and 12,145,420.25 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 | 48,581,681 | |
| -1 | 48,581,681 |
If you did it right, you will end up with this table:
| 1 | 23 | 31 | 61 | 713 | 1,117 | 1,403 | 1,891 | 25,691 | 34,627 | 43,493 | 68,137 | 796,421 | 1,567,151 | 2,112,247 | 48,581,681 |
| -1 | -23 | -31 | -61 | -713 | -1,117 | -1,403 | -1,891 | -25,691 | -34,627 | -43,493 | -68,137 | -796,421 | -1,567,151 | -2,112,247 | -48,581,681 |
