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 141,264,449, 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 | 141,264,449 | |
| -1 | -141,264,449 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,264,449.
Example:
1 x 141,264,449 = 141,264,449
and
-1 x -141,264,449 = 141,264,449
Notice both answers equal 141,264,449
With that explanation out of the way, let's continue. Next, we take the number 141,264,449 and divide it by 2:
141,264,449 ÷ 2 = 70,632,224.5
If the quotient is a whole number, then 2 and 70,632,224.5 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 | 141,264,449 | |
| -1 | -141,264,449 |
Now, we try dividing 141,264,449 by 3:
141,264,449 ÷ 3 = 47,088,149.6667
If the quotient is a whole number, then 3 and 47,088,149.6667 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 | 141,264,449 | |
| -1 | -141,264,449 |
Let's try dividing by 4:
141,264,449 ÷ 4 = 35,316,112.25
If the quotient is a whole number, then 4 and 35,316,112.25 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 | 141,264,449 | |
| -1 | 141,264,449 |
If you did it right, you will end up with this table:
| 1 | 19 | 89 | 139 | 601 | 1,691 | 2,641 | 11,419 | 12,371 | 53,489 | 83,539 | 235,049 | 1,016,291 | 1,587,241 | 7,434,971 | 141,264,449 |
| -1 | -19 | -89 | -139 | -601 | -1,691 | -2,641 | -11,419 | -12,371 | -53,489 | -83,539 | -235,049 | -1,016,291 | -1,587,241 | -7,434,971 | -141,264,449 |
