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 143,323,331, 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 | 143,323,331 | |
| -1 | -143,323,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,323,331.
Example:
1 x 143,323,331 = 143,323,331
and
-1 x -143,323,331 = 143,323,331
Notice both answers equal 143,323,331
With that explanation out of the way, let's continue. Next, we take the number 143,323,331 and divide it by 2:
143,323,331 ÷ 2 = 71,661,665.5
If the quotient is a whole number, then 2 and 71,661,665.5 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 | 143,323,331 | |
| -1 | -143,323,331 |
Now, we try dividing 143,323,331 by 3:
143,323,331 ÷ 3 = 47,774,443.6667
If the quotient is a whole number, then 3 and 47,774,443.6667 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 | 143,323,331 | |
| -1 | -143,323,331 |
Let's try dividing by 4:
143,323,331 ÷ 4 = 35,830,832.75
If the quotient is a whole number, then 4 and 35,830,832.75 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 | 143,323,331 | |
| -1 | 143,323,331 |
If you did it right, you will end up with this table:
| 1 | 41 | 59 | 179 | 331 | 2,419 | 7,339 | 10,561 | 13,571 | 19,529 | 59,249 | 433,001 | 800,689 | 2,429,209 | 3,495,691 | 143,323,331 |
| -1 | -41 | -59 | -179 | -331 | -2,419 | -7,339 | -10,561 | -13,571 | -19,529 | -59,249 | -433,001 | -800,689 | -2,429,209 | -3,495,691 | -143,323,331 |
