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 58,189,655, 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 | 58,189,655 | |
| -1 | -58,189,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 58,189,655.
Example:
1 x 58,189,655 = 58,189,655
and
-1 x -58,189,655 = 58,189,655
Notice both answers equal 58,189,655
With that explanation out of the way, let's continue. Next, we take the number 58,189,655 and divide it by 2:
58,189,655 ÷ 2 = 29,094,827.5
If the quotient is a whole number, then 2 and 29,094,827.5 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 | 58,189,655 | |
| -1 | -58,189,655 |
Now, we try dividing 58,189,655 by 3:
58,189,655 ÷ 3 = 19,396,551.6667
If the quotient is a whole number, then 3 and 19,396,551.6667 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 | 58,189,655 | |
| -1 | -58,189,655 |
Let's try dividing by 4:
58,189,655 ÷ 4 = 14,547,413.75
If the quotient is a whole number, then 4 and 14,547,413.75 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 | 58,189,655 | |
| -1 | 58,189,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 311 | 1,555 | 1,627 | 7,153 | 8,135 | 35,765 | 37,421 | 187,105 | 505,997 | 2,529,985 | 11,637,931 | 58,189,655 |
| -1 | -5 | -23 | -115 | -311 | -1,555 | -1,627 | -7,153 | -8,135 | -35,765 | -37,421 | -187,105 | -505,997 | -2,529,985 | -11,637,931 | -58,189,655 |
