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 141,440,321, 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 | 141,440,321 | |
| -1 | -141,440,321 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,440,321.
Example:
1 x 141,440,321 = 141,440,321
and
-1 x -141,440,321 = 141,440,321
Notice both answers equal 141,440,321
With that explanation out of the way, let's continue. Next, we take the number 141,440,321 and divide it by 2:
141,440,321 ÷ 2 = 70,720,160.5
If the quotient is a whole number, then 2 and 70,720,160.5 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 | 141,440,321 | |
| -1 | -141,440,321 |
Now, we try dividing 141,440,321 by 3:
141,440,321 ÷ 3 = 47,146,773.6667
If the quotient is a whole number, then 3 and 47,146,773.6667 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 | 141,440,321 | |
| -1 | -141,440,321 |
Let's try dividing by 4:
141,440,321 ÷ 4 = 35,360,080.25
If the quotient is a whole number, then 4 and 35,360,080.25 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 | 141,440,321 | |
| -1 | 141,440,321 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 103 | 341 | 1,133 | 3,193 | 4,027 | 35,123 | 44,297 | 124,837 | 414,781 | 1,373,207 | 4,562,591 | 12,858,211 | 141,440,321 |
| -1 | -11 | -31 | -103 | -341 | -1,133 | -3,193 | -4,027 | -35,123 | -44,297 | -124,837 | -414,781 | -1,373,207 | -4,562,591 | -12,858,211 | -141,440,321 |
