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 440,501,243, 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 | 440,501,243 | |
| -1 | -440,501,243 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 440,501,243.
Example:
1 x 440,501,243 = 440,501,243
and
-1 x -440,501,243 = 440,501,243
Notice both answers equal 440,501,243
With that explanation out of the way, let's continue. Next, we take the number 440,501,243 and divide it by 2:
440,501,243 ÷ 2 = 220,250,621.5
If the quotient is a whole number, then 2 and 220,250,621.5 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 | 440,501,243 | |
| -1 | -440,501,243 |
Now, we try dividing 440,501,243 by 3:
440,501,243 ÷ 3 = 146,833,747.6667
If the quotient is a whole number, then 3 and 146,833,747.6667 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 | 440,501,243 | |
| -1 | -440,501,243 |
Let's try dividing by 4:
440,501,243 ÷ 4 = 110,125,310.75
If the quotient is a whole number, then 4 and 110,125,310.75 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 | 440,501,243 | |
| -1 | 440,501,243 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 37 | 91 | 259 | 481 | 3,367 | 130,829 | 915,803 | 1,700,777 | 4,840,673 | 11,905,439 | 33,884,711 | 62,928,749 | 440,501,243 |
| -1 | -7 | -13 | -37 | -91 | -259 | -481 | -3,367 | -130,829 | -915,803 | -1,700,777 | -4,840,673 | -11,905,439 | -33,884,711 | -62,928,749 | -440,501,243 |
