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 258,250,343, 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 | 258,250,343 | |
| -1 | -258,250,343 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 258,250,343.
Example:
1 x 258,250,343 = 258,250,343
and
-1 x -258,250,343 = 258,250,343
Notice both answers equal 258,250,343
With that explanation out of the way, let's continue. Next, we take the number 258,250,343 and divide it by 2:
258,250,343 ÷ 2 = 129,125,171.5
If the quotient is a whole number, then 2 and 129,125,171.5 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 | 258,250,343 | |
| -1 | -258,250,343 |
Now, we try dividing 258,250,343 by 3:
258,250,343 ÷ 3 = 86,083,447.6667
If the quotient is a whole number, then 3 and 86,083,447.6667 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 | 258,250,343 | |
| -1 | -258,250,343 |
Let's try dividing by 4:
258,250,343 ÷ 4 = 64,562,585.75
If the quotient is a whole number, then 4 and 64,562,585.75 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 | 258,250,343 | |
| -1 | 258,250,343 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 137 | 481 | 1,781 | 3,919 | 5,069 | 50,947 | 65,897 | 145,003 | 536,903 | 1,885,039 | 6,979,739 | 19,865,411 | 258,250,343 |
| -1 | -13 | -37 | -137 | -481 | -1,781 | -3,919 | -5,069 | -50,947 | -65,897 | -145,003 | -536,903 | -1,885,039 | -6,979,739 | -19,865,411 | -258,250,343 |
