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 143,341,231, 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 | 143,341,231 | |
| -1 | -143,341,231 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,341,231.
Example:
1 x 143,341,231 = 143,341,231
and
-1 x -143,341,231 = 143,341,231
Notice both answers equal 143,341,231
With that explanation out of the way, let's continue. Next, we take the number 143,341,231 and divide it by 2:
143,341,231 ÷ 2 = 71,670,615.5
If the quotient is a whole number, then 2 and 71,670,615.5 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 | 143,341,231 | |
| -1 | -143,341,231 |
Now, we try dividing 143,341,231 by 3:
143,341,231 ÷ 3 = 47,780,410.3333
If the quotient is a whole number, then 3 and 47,780,410.3333 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 | 143,341,231 | |
| -1 | -143,341,231 |
Let's try dividing by 4:
143,341,231 ÷ 4 = 35,835,307.75
If the quotient is a whole number, then 4 and 35,835,307.75 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 | 143,341,231 | |
| -1 | 143,341,231 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 179 | 473 | 1,693 | 1,969 | 7,697 | 18,623 | 72,799 | 84,667 | 303,047 | 800,789 | 3,333,517 | 13,031,021 | 143,341,231 |
| -1 | -11 | -43 | -179 | -473 | -1,693 | -1,969 | -7,697 | -18,623 | -72,799 | -84,667 | -303,047 | -800,789 | -3,333,517 | -13,031,021 | -143,341,231 |
