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 440,133,991, 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 | 440,133,991 | |
| -1 | -440,133,991 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 440,133,991.
Example:
1 x 440,133,991 = 440,133,991
and
-1 x -440,133,991 = 440,133,991
Notice both answers equal 440,133,991
With that explanation out of the way, let's continue. Next, we take the number 440,133,991 and divide it by 2:
440,133,991 ÷ 2 = 220,066,995.5
If the quotient is a whole number, then 2 and 220,066,995.5 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 | 440,133,991 | |
| -1 | -440,133,991 |
Now, we try dividing 440,133,991 by 3:
440,133,991 ÷ 3 = 146,711,330.3333
If the quotient is a whole number, then 3 and 146,711,330.3333 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 | 440,133,991 | |
| -1 | -440,133,991 |
Let's try dividing by 4:
440,133,991 ÷ 4 = 110,033,497.75
If the quotient is a whole number, then 4 and 110,033,497.75 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 | 440,133,991 | |
| -1 | 440,133,991 |
If you did it right, you will end up with this table:
| 1 | 11 | 47 | 121 | 193 | 401 | 517 | 2,123 | 4,411 | 5,687 | 9,071 | 18,847 | 23,353 | 48,521 | 77,393 | 99,781 | 207,317 | 851,323 | 1,097,591 | 2,280,487 | 3,637,471 | 9,364,553 | 40,012,181 | 440,133,991 |
| -1 | -11 | -47 | -121 | -193 | -401 | -517 | -2,123 | -4,411 | -5,687 | -9,071 | -18,847 | -23,353 | -48,521 | -77,393 | -99,781 | -207,317 | -851,323 | -1,097,591 | -2,280,487 | -3,637,471 | -9,364,553 | -40,012,181 | -440,133,991 |
