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 258,628,463, 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 | 258,628,463 | |
| -1 | -258,628,463 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 258,628,463.
Example:
1 x 258,628,463 = 258,628,463
and
-1 x -258,628,463 = 258,628,463
Notice both answers equal 258,628,463
With that explanation out of the way, let's continue. Next, we take the number 258,628,463 and divide it by 2:
258,628,463 ÷ 2 = 129,314,231.5
If the quotient is a whole number, then 2 and 129,314,231.5 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 | 258,628,463 | |
| -1 | -258,628,463 |
Now, we try dividing 258,628,463 by 3:
258,628,463 ÷ 3 = 86,209,487.6667
If the quotient is a whole number, then 3 and 86,209,487.6667 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 | 258,628,463 | |
| -1 | -258,628,463 |
Let's try dividing by 4:
258,628,463 ÷ 4 = 64,657,115.75
If the quotient is a whole number, then 4 and 64,657,115.75 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 | 258,628,463 | |
| -1 | 258,628,463 |
If you did it right, you will end up with this table:
| 1 | 17 | 137 | 293 | 379 | 2,329 | 4,981 | 6,443 | 40,141 | 51,923 | 111,047 | 682,397 | 882,691 | 1,887,799 | 15,213,439 | 258,628,463 |
| -1 | -17 | -137 | -293 | -379 | -2,329 | -4,981 | -6,443 | -40,141 | -51,923 | -111,047 | -682,397 | -882,691 | -1,887,799 | -15,213,439 | -258,628,463 |
