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 141,567,605, 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 | 141,567,605 | |
| -1 | -141,567,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,567,605.
Example:
1 x 141,567,605 = 141,567,605
and
-1 x -141,567,605 = 141,567,605
Notice both answers equal 141,567,605
With that explanation out of the way, let's continue. Next, we take the number 141,567,605 and divide it by 2:
141,567,605 ÷ 2 = 70,783,802.5
If the quotient is a whole number, then 2 and 70,783,802.5 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 | 141,567,605 | |
| -1 | -141,567,605 |
Now, we try dividing 141,567,605 by 3:
141,567,605 ÷ 3 = 47,189,201.6667
If the quotient is a whole number, then 3 and 47,189,201.6667 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 | 141,567,605 | |
| -1 | -141,567,605 |
Let's try dividing by 4:
141,567,605 ÷ 4 = 35,391,901.25
If the quotient is a whole number, then 4 and 35,391,901.25 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 | 141,567,605 | |
| -1 | 141,567,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 79 | 199 | 395 | 995 | 1,801 | 9,005 | 15,721 | 78,605 | 142,279 | 358,399 | 711,395 | 1,791,995 | 28,313,521 | 141,567,605 |
| -1 | -5 | -79 | -199 | -395 | -995 | -1,801 | -9,005 | -15,721 | -78,605 | -142,279 | -358,399 | -711,395 | -1,791,995 | -28,313,521 | -141,567,605 |
