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 143,331,239, 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 | 143,331,239 | |
| -1 | -143,331,239 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,331,239.
Example:
1 x 143,331,239 = 143,331,239
and
-1 x -143,331,239 = 143,331,239
Notice both answers equal 143,331,239
With that explanation out of the way, let's continue. Next, we take the number 143,331,239 and divide it by 2:
143,331,239 ÷ 2 = 71,665,619.5
If the quotient is a whole number, then 2 and 71,665,619.5 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 | 143,331,239 | |
| -1 | -143,331,239 |
Now, we try dividing 143,331,239 by 3:
143,331,239 ÷ 3 = 47,777,079.6667
If the quotient is a whole number, then 3 and 47,777,079.6667 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 | 143,331,239 | |
| -1 | -143,331,239 |
Let's try dividing by 4:
143,331,239 ÷ 4 = 35,832,809.75
If the quotient is a whole number, then 4 and 35,832,809.75 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 | 143,331,239 | |
| -1 | 143,331,239 |
If you did it right, you will end up with this table:
| 1 | 23 | 53 | 307 | 383 | 1,219 | 7,061 | 8,809 | 16,271 | 20,299 | 117,581 | 374,233 | 466,877 | 2,704,363 | 6,231,793 | 143,331,239 |
| -1 | -23 | -53 | -307 | -383 | -1,219 | -7,061 | -8,809 | -16,271 | -20,299 | -117,581 | -374,233 | -466,877 | -2,704,363 | -6,231,793 | -143,331,239 |
