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 5,615,533, 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 | 5,615,533 | |
| -1 | -5,615,533 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,615,533.
Example:
1 x 5,615,533 = 5,615,533
and
-1 x -5,615,533 = 5,615,533
Notice both answers equal 5,615,533
With that explanation out of the way, let's continue. Next, we take the number 5,615,533 and divide it by 2:
5,615,533 ÷ 2 = 2,807,766.5
If the quotient is a whole number, then 2 and 2,807,766.5 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 | 5,615,533 | |
| -1 | -5,615,533 |
Now, we try dividing 5,615,533 by 3:
5,615,533 ÷ 3 = 1,871,844.3333
If the quotient is a whole number, then 3 and 1,871,844.3333 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 | 5,615,533 | |
| -1 | -5,615,533 |
Let's try dividing by 4:
5,615,533 ÷ 4 = 1,403,883.25
If the quotient is a whole number, then 4 and 1,403,883.25 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 | 5,615,533 | |
| -1 | 5,615,533 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 233 | 313 | 1,631 | 2,191 | 2,563 | 3,443 | 17,941 | 24,101 | 72,929 | 510,503 | 802,219 | 5,615,533 |
| -1 | -7 | -11 | -77 | -233 | -313 | -1,631 | -2,191 | -2,563 | -3,443 | -17,941 | -24,101 | -72,929 | -510,503 | -802,219 | -5,615,533 |
