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 440,456,645, 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 | 440,456,645 | |
| -1 | -440,456,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 440,456,645.
Example:
1 x 440,456,645 = 440,456,645
and
-1 x -440,456,645 = 440,456,645
Notice both answers equal 440,456,645
With that explanation out of the way, let's continue. Next, we take the number 440,456,645 and divide it by 2:
440,456,645 ÷ 2 = 220,228,322.5
If the quotient is a whole number, then 2 and 220,228,322.5 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 | 440,456,645 | |
| -1 | -440,456,645 |
Now, we try dividing 440,456,645 by 3:
440,456,645 ÷ 3 = 146,818,881.6667
If the quotient is a whole number, then 3 and 146,818,881.6667 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 | 440,456,645 | |
| -1 | -440,456,645 |
Let's try dividing by 4:
440,456,645 ÷ 4 = 110,114,161.25
If the quotient is a whole number, then 4 and 110,114,161.25 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 | 440,456,645 | |
| -1 | 440,456,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 205 | 293 | 1,465 | 7,333 | 12,013 | 36,665 | 60,065 | 300,653 | 1,503,265 | 2,148,569 | 10,742,845 | 88,091,329 | 440,456,645 |
| -1 | -5 | -41 | -205 | -293 | -1,465 | -7,333 | -12,013 | -36,665 | -60,065 | -300,653 | -1,503,265 | -2,148,569 | -10,742,845 | -88,091,329 | -440,456,645 |
