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 143,145,233, 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 | 143,145,233 | |
| -1 | -143,145,233 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,145,233.
Example:
1 x 143,145,233 = 143,145,233
and
-1 x -143,145,233 = 143,145,233
Notice both answers equal 143,145,233
With that explanation out of the way, let's continue. Next, we take the number 143,145,233 and divide it by 2:
143,145,233 ÷ 2 = 71,572,616.5
If the quotient is a whole number, then 2 and 71,572,616.5 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 | 143,145,233 | |
| -1 | -143,145,233 |
Now, we try dividing 143,145,233 by 3:
143,145,233 ÷ 3 = 47,715,077.6667
If the quotient is a whole number, then 3 and 47,715,077.6667 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 | 143,145,233 | |
| -1 | -143,145,233 |
Let's try dividing by 4:
143,145,233 ÷ 4 = 35,786,308.25
If the quotient is a whole number, then 4 and 35,786,308.25 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 | 143,145,233 | |
| -1 | 143,145,233 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 587 | 3,167 | 4,109 | 6,457 | 22,169 | 34,837 | 45,199 | 243,859 | 1,859,029 | 13,013,203 | 20,449,319 | 143,145,233 |
| -1 | -7 | -11 | -77 | -587 | -3,167 | -4,109 | -6,457 | -22,169 | -34,837 | -45,199 | -243,859 | -1,859,029 | -13,013,203 | -20,449,319 | -143,145,233 |
