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 58,478,587, 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 | 58,478,587 | |
| -1 | -58,478,587 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 58,478,587.
Example:
1 x 58,478,587 = 58,478,587
and
-1 x -58,478,587 = 58,478,587
Notice both answers equal 58,478,587
With that explanation out of the way, let's continue. Next, we take the number 58,478,587 and divide it by 2:
58,478,587 ÷ 2 = 29,239,293.5
If the quotient is a whole number, then 2 and 29,239,293.5 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 | 58,478,587 | |
| -1 | -58,478,587 |
Now, we try dividing 58,478,587 by 3:
58,478,587 ÷ 3 = 19,492,862.3333
If the quotient is a whole number, then 3 and 19,492,862.3333 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 | 58,478,587 | |
| -1 | -58,478,587 |
Let's try dividing by 4:
58,478,587 ÷ 4 = 14,619,646.75
If the quotient is a whole number, then 4 and 14,619,646.75 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 | 58,478,587 | |
| -1 | 58,478,587 |
If you did it right, you will end up with this table:
| 1 | 29 | 41 | 137 | 359 | 1,189 | 3,973 | 5,617 | 10,411 | 14,719 | 49,183 | 162,893 | 426,851 | 1,426,307 | 2,016,503 | 58,478,587 |
| -1 | -29 | -41 | -137 | -359 | -1,189 | -3,973 | -5,617 | -10,411 | -14,719 | -49,183 | -162,893 | -426,851 | -1,426,307 | -2,016,503 | -58,478,587 |
