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 141,224,405, 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 | 141,224,405 | |
| -1 | -141,224,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,224,405.
Example:
1 x 141,224,405 = 141,224,405
and
-1 x -141,224,405 = 141,224,405
Notice both answers equal 141,224,405
With that explanation out of the way, let's continue. Next, we take the number 141,224,405 and divide it by 2:
141,224,405 ÷ 2 = 70,612,202.5
If the quotient is a whole number, then 2 and 70,612,202.5 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 | 141,224,405 | |
| -1 | -141,224,405 |
Now, we try dividing 141,224,405 by 3:
141,224,405 ÷ 3 = 47,074,801.6667
If the quotient is a whole number, then 3 and 47,074,801.6667 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 | 141,224,405 | |
| -1 | -141,224,405 |
Let's try dividing by 4:
141,224,405 ÷ 4 = 35,306,101.25
If the quotient is a whole number, then 4 and 35,306,101.25 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 | 141,224,405 | |
| -1 | 141,224,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,061 | 3,803 | 5,305 | 7,427 | 19,015 | 26,621 | 37,135 | 133,105 | 4,034,983 | 20,174,915 | 28,244,881 | 141,224,405 |
| -1 | -5 | -7 | -35 | -1,061 | -3,803 | -5,305 | -7,427 | -19,015 | -26,621 | -37,135 | -133,105 | -4,034,983 | -20,174,915 | -28,244,881 | -141,224,405 |
