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 5,623,865, 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 | 5,623,865 | |
| -1 | -5,623,865 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,623,865.
Example:
1 x 5,623,865 = 5,623,865
and
-1 x -5,623,865 = 5,623,865
Notice both answers equal 5,623,865
With that explanation out of the way, let's continue. Next, we take the number 5,623,865 and divide it by 2:
5,623,865 ÷ 2 = 2,811,932.5
If the quotient is a whole number, then 2 and 2,811,932.5 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 | 5,623,865 | |
| -1 | -5,623,865 |
Now, we try dividing 5,623,865 by 3:
5,623,865 ÷ 3 = 1,874,621.6667
If the quotient is a whole number, then 3 and 1,874,621.6667 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 | 5,623,865 | |
| -1 | -5,623,865 |
Let's try dividing by 4:
5,623,865 ÷ 4 = 1,405,966.25
If the quotient is a whole number, then 4 and 1,405,966.25 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 | 5,623,865 | |
| -1 | 5,623,865 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 31 | 65 | 155 | 403 | 2,015 | 2,791 | 13,955 | 36,283 | 86,521 | 181,415 | 432,605 | 1,124,773 | 5,623,865 |
| -1 | -5 | -13 | -31 | -65 | -155 | -403 | -2,015 | -2,791 | -13,955 | -36,283 | -86,521 | -181,415 | -432,605 | -1,124,773 | -5,623,865 |
