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 404,500,243, 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 | 404,500,243 | |
| -1 | -404,500,243 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 404,500,243.
Example:
1 x 404,500,243 = 404,500,243
and
-1 x -404,500,243 = 404,500,243
Notice both answers equal 404,500,243
With that explanation out of the way, let's continue. Next, we take the number 404,500,243 and divide it by 2:
404,500,243 ÷ 2 = 202,250,121.5
If the quotient is a whole number, then 2 and 202,250,121.5 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 | 404,500,243 | |
| -1 | -404,500,243 |
Now, we try dividing 404,500,243 by 3:
404,500,243 ÷ 3 = 134,833,414.3333
If the quotient is a whole number, then 3 and 134,833,414.3333 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 | 404,500,243 | |
| -1 | -404,500,243 |
Let's try dividing by 4:
404,500,243 ÷ 4 = 101,125,060.75
If the quotient is a whole number, then 4 and 101,125,060.75 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 | 404,500,243 | |
| -1 | 404,500,243 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 49 | 259 | 343 | 1,813 | 12,691 | 31,873 | 223,111 | 1,179,301 | 1,561,777 | 8,255,107 | 10,932,439 | 57,785,749 | 404,500,243 |
| -1 | -7 | -37 | -49 | -259 | -343 | -1,813 | -12,691 | -31,873 | -223,111 | -1,179,301 | -1,561,777 | -8,255,107 | -10,932,439 | -57,785,749 | -404,500,243 |
