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 4,420,787, 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 | 4,420,787 | |
| -1 | -4,420,787 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,420,787.
Example:
1 x 4,420,787 = 4,420,787
and
-1 x -4,420,787 = 4,420,787
Notice both answers equal 4,420,787
With that explanation out of the way, let's continue. Next, we take the number 4,420,787 and divide it by 2:
4,420,787 ÷ 2 = 2,210,393.5
If the quotient is a whole number, then 2 and 2,210,393.5 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 | 4,420,787 | |
| -1 | -4,420,787 |
Now, we try dividing 4,420,787 by 3:
4,420,787 ÷ 3 = 1,473,595.6667
If the quotient is a whole number, then 3 and 1,473,595.6667 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 | 4,420,787 | |
| -1 | -4,420,787 |
Let's try dividing by 4:
4,420,787 ÷ 4 = 1,105,196.75
If the quotient is a whole number, then 4 and 1,105,196.75 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 | 4,420,787 | |
| -1 | 4,420,787 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 43 | 133 | 301 | 773 | 817 | 5,411 | 5,719 | 14,687 | 33,239 | 102,809 | 232,673 | 631,541 | 4,420,787 |
| -1 | -7 | -19 | -43 | -133 | -301 | -773 | -817 | -5,411 | -5,719 | -14,687 | -33,239 | -102,809 | -232,673 | -631,541 | -4,420,787 |
