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 48,073,115, 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 | 48,073,115 | |
| -1 | -48,073,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 48,073,115.
Example:
1 x 48,073,115 = 48,073,115
and
-1 x -48,073,115 = 48,073,115
Notice both answers equal 48,073,115
With that explanation out of the way, let's continue. Next, we take the number 48,073,115 and divide it by 2:
48,073,115 ÷ 2 = 24,036,557.5
If the quotient is a whole number, then 2 and 24,036,557.5 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 | 48,073,115 | |
| -1 | -48,073,115 |
Now, we try dividing 48,073,115 by 3:
48,073,115 ÷ 3 = 16,024,371.6667
If the quotient is a whole number, then 3 and 16,024,371.6667 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 | 48,073,115 | |
| -1 | -48,073,115 |
Let's try dividing by 4:
48,073,115 ÷ 4 = 12,018,278.75
If the quotient is a whole number, then 4 and 12,018,278.75 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 | 48,073,115 | |
| -1 | 48,073,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 151 | 205 | 755 | 1,553 | 6,191 | 7,765 | 30,955 | 63,673 | 234,503 | 318,365 | 1,172,515 | 9,614,623 | 48,073,115 |
| -1 | -5 | -41 | -151 | -205 | -755 | -1,553 | -6,191 | -7,765 | -30,955 | -63,673 | -234,503 | -318,365 | -1,172,515 | -9,614,623 | -48,073,115 |
