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 404,224,045, 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 | 404,224,045 | |
| -1 | -404,224,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 404,224,045.
Example:
1 x 404,224,045 = 404,224,045
and
-1 x -404,224,045 = 404,224,045
Notice both answers equal 404,224,045
With that explanation out of the way, let's continue. Next, we take the number 404,224,045 and divide it by 2:
404,224,045 ÷ 2 = 202,112,022.5
If the quotient is a whole number, then 2 and 202,112,022.5 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 | 404,224,045 | |
| -1 | -404,224,045 |
Now, we try dividing 404,224,045 by 3:
404,224,045 ÷ 3 = 134,741,348.3333
If the quotient is a whole number, then 3 and 134,741,348.3333 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 | 404,224,045 | |
| -1 | -404,224,045 |
Let's try dividing by 4:
404,224,045 ÷ 4 = 101,056,011.25
If the quotient is a whole number, then 4 and 101,056,011.25 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 | 404,224,045 | |
| -1 | 404,224,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 59 | 85 | 295 | 1,003 | 5,015 | 80,603 | 403,015 | 1,370,251 | 4,755,577 | 6,851,255 | 23,777,885 | 80,844,809 | 404,224,045 |
| -1 | -5 | -17 | -59 | -85 | -295 | -1,003 | -5,015 | -80,603 | -403,015 | -1,370,251 | -4,755,577 | -6,851,255 | -23,777,885 | -80,844,809 | -404,224,045 |
