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 58,578,779, 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 | 58,578,779 | |
| -1 | -58,578,779 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 58,578,779.
Example:
1 x 58,578,779 = 58,578,779
and
-1 x -58,578,779 = 58,578,779
Notice both answers equal 58,578,779
With that explanation out of the way, let's continue. Next, we take the number 58,578,779 and divide it by 2:
58,578,779 ÷ 2 = 29,289,389.5
If the quotient is a whole number, then 2 and 29,289,389.5 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 | 58,578,779 | |
| -1 | -58,578,779 |
Now, we try dividing 58,578,779 by 3:
58,578,779 ÷ 3 = 19,526,259.6667
If the quotient is a whole number, then 3 and 19,526,259.6667 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 | 58,578,779 | |
| -1 | -58,578,779 |
Let's try dividing by 4:
58,578,779 ÷ 4 = 14,644,694.75
If the quotient is a whole number, then 4 and 14,644,694.75 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 | 58,578,779 | |
| -1 | 58,578,779 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 263 | 329 | 677 | 1,841 | 4,739 | 12,361 | 31,819 | 86,527 | 178,051 | 222,733 | 1,246,357 | 8,368,397 | 58,578,779 |
| -1 | -7 | -47 | -263 | -329 | -677 | -1,841 | -4,739 | -12,361 | -31,819 | -86,527 | -178,051 | -222,733 | -1,246,357 | -8,368,397 | -58,578,779 |
