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 141,828,799, 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 | 141,828,799 | |
| -1 | -141,828,799 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,828,799.
Example:
1 x 141,828,799 = 141,828,799
and
-1 x -141,828,799 = 141,828,799
Notice both answers equal 141,828,799
With that explanation out of the way, let's continue. Next, we take the number 141,828,799 and divide it by 2:
141,828,799 ÷ 2 = 70,914,399.5
If the quotient is a whole number, then 2 and 70,914,399.5 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 | 141,828,799 | |
| -1 | -141,828,799 |
Now, we try dividing 141,828,799 by 3:
141,828,799 ÷ 3 = 47,276,266.3333
If the quotient is a whole number, then 3 and 47,276,266.3333 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 | 141,828,799 | |
| -1 | -141,828,799 |
Let's try dividing by 4:
141,828,799 ÷ 4 = 35,457,199.75
If the quotient is a whole number, then 4 and 35,457,199.75 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 | 141,828,799 | |
| -1 | 141,828,799 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 263 | 287 | 1,841 | 1,879 | 10,783 | 13,153 | 75,481 | 77,039 | 494,177 | 539,273 | 3,459,239 | 20,261,257 | 141,828,799 |
| -1 | -7 | -41 | -263 | -287 | -1,841 | -1,879 | -10,783 | -13,153 | -75,481 | -77,039 | -494,177 | -539,273 | -3,459,239 | -20,261,257 | -141,828,799 |
