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 234,003,407, 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 | 234,003,407 | |
| -1 | -234,003,407 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 234,003,407.
Example:
1 x 234,003,407 = 234,003,407
and
-1 x -234,003,407 = 234,003,407
Notice both answers equal 234,003,407
With that explanation out of the way, let's continue. Next, we take the number 234,003,407 and divide it by 2:
234,003,407 ÷ 2 = 117,001,703.5
If the quotient is a whole number, then 2 and 117,001,703.5 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 | 234,003,407 | |
| -1 | -234,003,407 |
Now, we try dividing 234,003,407 by 3:
234,003,407 ÷ 3 = 78,001,135.6667
If the quotient is a whole number, then 3 and 78,001,135.6667 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 | 234,003,407 | |
| -1 | -234,003,407 |
Let's try dividing by 4:
234,003,407 ÷ 4 = 58,500,851.75
If the quotient is a whole number, then 4 and 58,500,851.75 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 | 234,003,407 | |
| -1 | 234,003,407 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 31 | 319 | 341 | 899 | 9,889 | 23,663 | 260,293 | 686,227 | 733,553 | 7,548,497 | 8,069,083 | 21,273,037 | 234,003,407 |
| -1 | -11 | -29 | -31 | -319 | -341 | -899 | -9,889 | -23,663 | -260,293 | -686,227 | -733,553 | -7,548,497 | -8,069,083 | -21,273,037 | -234,003,407 |
