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 143,441,221, 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 | 143,441,221 | |
| -1 | -143,441,221 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,441,221.
Example:
1 x 143,441,221 = 143,441,221
and
-1 x -143,441,221 = 143,441,221
Notice both answers equal 143,441,221
With that explanation out of the way, let's continue. Next, we take the number 143,441,221 and divide it by 2:
143,441,221 ÷ 2 = 71,720,610.5
If the quotient is a whole number, then 2 and 71,720,610.5 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 | 143,441,221 | |
| -1 | -143,441,221 |
Now, we try dividing 143,441,221 by 3:
143,441,221 ÷ 3 = 47,813,740.3333
If the quotient is a whole number, then 3 and 47,813,740.3333 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 | 143,441,221 | |
| -1 | -143,441,221 |
Let's try dividing by 4:
143,441,221 ÷ 4 = 35,860,305.25
If the quotient is a whole number, then 4 and 35,860,305.25 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 | 143,441,221 | |
| -1 | 143,441,221 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 29 | 77 | 203 | 319 | 2,233 | 64,237 | 449,659 | 706,607 | 1,862,873 | 4,946,249 | 13,040,111 | 20,491,603 | 143,441,221 |
| -1 | -7 | -11 | -29 | -77 | -203 | -319 | -2,233 | -64,237 | -449,659 | -706,607 | -1,862,873 | -4,946,249 | -13,040,111 | -20,491,603 | -143,441,221 |
