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 143,401,235, 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 | 143,401,235 | |
| -1 | -143,401,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,401,235.
Example:
1 x 143,401,235 = 143,401,235
and
-1 x -143,401,235 = 143,401,235
Notice both answers equal 143,401,235
With that explanation out of the way, let's continue. Next, we take the number 143,401,235 and divide it by 2:
143,401,235 ÷ 2 = 71,700,617.5
If the quotient is a whole number, then 2 and 71,700,617.5 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 | 143,401,235 | |
| -1 | -143,401,235 |
Now, we try dividing 143,401,235 by 3:
143,401,235 ÷ 3 = 47,800,411.6667
If the quotient is a whole number, then 3 and 47,800,411.6667 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 | 143,401,235 | |
| -1 | -143,401,235 |
Let's try dividing by 4:
143,401,235 ÷ 4 = 35,850,308.75
If the quotient is a whole number, then 4 and 35,850,308.75 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 | 143,401,235 | |
| -1 | 143,401,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 103 | 307 | 515 | 907 | 1,535 | 4,535 | 31,621 | 93,421 | 158,105 | 278,449 | 467,105 | 1,392,245 | 28,680,247 | 143,401,235 |
| -1 | -5 | -103 | -307 | -515 | -907 | -1,535 | -4,535 | -31,621 | -93,421 | -158,105 | -278,449 | -467,105 | -1,392,245 | -28,680,247 | -143,401,235 |
