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 143,481,821, 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 | 143,481,821 | |
| -1 | -143,481,821 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,481,821.
Example:
1 x 143,481,821 = 143,481,821
and
-1 x -143,481,821 = 143,481,821
Notice both answers equal 143,481,821
With that explanation out of the way, let's continue. Next, we take the number 143,481,821 and divide it by 2:
143,481,821 ÷ 2 = 71,740,910.5
If the quotient is a whole number, then 2 and 71,740,910.5 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 | 143,481,821 | |
| -1 | -143,481,821 |
Now, we try dividing 143,481,821 by 3:
143,481,821 ÷ 3 = 47,827,273.6667
If the quotient is a whole number, then 3 and 47,827,273.6667 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 | 143,481,821 | |
| -1 | -143,481,821 |
Let's try dividing by 4:
143,481,821 ÷ 4 = 35,870,455.25
If the quotient is a whole number, then 4 and 35,870,455.25 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 | 143,481,821 | |
| -1 | 143,481,821 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 61 | 203 | 427 | 1,769 | 11,587 | 12,383 | 81,109 | 336,023 | 706,807 | 2,352,161 | 4,947,649 | 20,497,403 | 143,481,821 |
| -1 | -7 | -29 | -61 | -203 | -427 | -1,769 | -11,587 | -12,383 | -81,109 | -336,023 | -706,807 | -2,352,161 | -4,947,649 | -20,497,403 | -143,481,821 |
