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 141,013,115, 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 | 141,013,115 | |
| -1 | -141,013,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,013,115.
Example:
1 x 141,013,115 = 141,013,115
and
-1 x -141,013,115 = 141,013,115
Notice both answers equal 141,013,115
With that explanation out of the way, let's continue. Next, we take the number 141,013,115 and divide it by 2:
141,013,115 ÷ 2 = 70,506,557.5
If the quotient is a whole number, then 2 and 70,506,557.5 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 | 141,013,115 | |
| -1 | -141,013,115 |
Now, we try dividing 141,013,115 by 3:
141,013,115 ÷ 3 = 47,004,371.6667
If the quotient is a whole number, then 3 and 47,004,371.6667 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 | 141,013,115 | |
| -1 | -141,013,115 |
Let's try dividing by 4:
141,013,115 ÷ 4 = 35,253,278.75
If the quotient is a whole number, then 4 and 35,253,278.75 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 | 141,013,115 | |
| -1 | 141,013,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 643 | 1,907 | 3,215 | 9,535 | 14,789 | 43,861 | 73,945 | 219,305 | 1,226,201 | 6,131,005 | 28,202,623 | 141,013,115 |
| -1 | -5 | -23 | -115 | -643 | -1,907 | -3,215 | -9,535 | -14,789 | -43,861 | -73,945 | -219,305 | -1,226,201 | -6,131,005 | -28,202,623 | -141,013,115 |
