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 228,671,443, 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 | 228,671,443 | |
| -1 | -228,671,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 228,671,443.
Example:
1 x 228,671,443 = 228,671,443
and
-1 x -228,671,443 = 228,671,443
Notice both answers equal 228,671,443
With that explanation out of the way, let's continue. Next, we take the number 228,671,443 and divide it by 2:
228,671,443 ÷ 2 = 114,335,721.5
If the quotient is a whole number, then 2 and 114,335,721.5 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 | 228,671,443 | |
| -1 | -228,671,443 |
Now, we try dividing 228,671,443 by 3:
228,671,443 ÷ 3 = 76,223,814.3333
If the quotient is a whole number, then 3 and 76,223,814.3333 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 | 228,671,443 | |
| -1 | -228,671,443 |
Let's try dividing by 4:
228,671,443 ÷ 4 = 57,167,860.75
If the quotient is a whole number, then 4 and 57,167,860.75 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 | 228,671,443 | |
| -1 | 228,671,443 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 1,001 | 228,443 | 1,599,101 | 2,512,873 | 2,969,759 | 17,590,111 | 20,788,313 | 32,667,349 | 228,671,443 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -1,001 | -228,443 | -1,599,101 | -2,512,873 | -2,969,759 | -17,590,111 | -20,788,313 | -32,667,349 | -228,671,443 |
