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 4,227,665, 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 | 4,227,665 | |
| -1 | -4,227,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,227,665.
Example:
1 x 4,227,665 = 4,227,665
and
-1 x -4,227,665 = 4,227,665
Notice both answers equal 4,227,665
With that explanation out of the way, let's continue. Next, we take the number 4,227,665 and divide it by 2:
4,227,665 ÷ 2 = 2,113,832.5
If the quotient is a whole number, then 2 and 2,113,832.5 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 | 4,227,665 | |
| -1 | -4,227,665 |
Now, we try dividing 4,227,665 by 3:
4,227,665 ÷ 3 = 1,409,221.6667
If the quotient is a whole number, then 3 and 1,409,221.6667 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 | 4,227,665 | |
| -1 | -4,227,665 |
Let's try dividing by 4:
4,227,665 ÷ 4 = 1,056,916.25
If the quotient is a whole number, then 4 and 1,056,916.25 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 | 4,227,665 | |
| -1 | 4,227,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 193 | 337 | 965 | 1,685 | 2,509 | 4,381 | 12,545 | 21,905 | 65,041 | 325,205 | 845,533 | 4,227,665 |
| -1 | -5 | -13 | -65 | -193 | -337 | -965 | -1,685 | -2,509 | -4,381 | -12,545 | -21,905 | -65,041 | -325,205 | -845,533 | -4,227,665 |
