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 58,011,785, 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 | 58,011,785 | |
| -1 | -58,011,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 58,011,785.
Example:
1 x 58,011,785 = 58,011,785
and
-1 x -58,011,785 = 58,011,785
Notice both answers equal 58,011,785
With that explanation out of the way, let's continue. Next, we take the number 58,011,785 and divide it by 2:
58,011,785 ÷ 2 = 29,005,892.5
If the quotient is a whole number, then 2 and 29,005,892.5 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 | 58,011,785 | |
| -1 | -58,011,785 |
Now, we try dividing 58,011,785 by 3:
58,011,785 ÷ 3 = 19,337,261.6667
If the quotient is a whole number, then 3 and 19,337,261.6667 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 | 58,011,785 | |
| -1 | -58,011,785 |
Let's try dividing by 4:
58,011,785 ÷ 4 = 14,502,946.25
If the quotient is a whole number, then 4 and 14,502,946.25 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 | 58,011,785 | |
| -1 | 58,011,785 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 169 | 845 | 2,197 | 5,281 | 10,985 | 26,405 | 68,653 | 343,265 | 892,489 | 4,462,445 | 11,602,357 | 58,011,785 |
| -1 | -5 | -13 | -65 | -169 | -845 | -2,197 | -5,281 | -10,985 | -26,405 | -68,653 | -343,265 | -892,489 | -4,462,445 | -11,602,357 | -58,011,785 |
