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 234,426,413, 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 | 234,426,413 | |
| -1 | -234,426,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 234,426,413.
Example:
1 x 234,426,413 = 234,426,413
and
-1 x -234,426,413 = 234,426,413
Notice both answers equal 234,426,413
With that explanation out of the way, let's continue. Next, we take the number 234,426,413 and divide it by 2:
234,426,413 ÷ 2 = 117,213,206.5
If the quotient is a whole number, then 2 and 117,213,206.5 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 | 234,426,413 | |
| -1 | -234,426,413 |
Now, we try dividing 234,426,413 by 3:
234,426,413 ÷ 3 = 78,142,137.6667
If the quotient is a whole number, then 3 and 78,142,137.6667 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 | 234,426,413 | |
| -1 | -234,426,413 |
Let's try dividing by 4:
234,426,413 ÷ 4 = 58,606,603.25
If the quotient is a whole number, then 4 and 58,606,603.25 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 | 234,426,413 | |
| -1 | 234,426,413 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 37 | 221 | 481 | 629 | 8,177 | 28,669 | 372,697 | 487,373 | 1,060,753 | 6,335,849 | 13,789,789 | 18,032,801 | 234,426,413 |
| -1 | -13 | -17 | -37 | -221 | -481 | -629 | -8,177 | -28,669 | -372,697 | -487,373 | -1,060,753 | -6,335,849 | -13,789,789 | -18,032,801 | -234,426,413 |
