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 5,385,413, 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 | 5,385,413 | |
| -1 | -5,385,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,385,413.
Example:
1 x 5,385,413 = 5,385,413
and
-1 x -5,385,413 = 5,385,413
Notice both answers equal 5,385,413
With that explanation out of the way, let's continue. Next, we take the number 5,385,413 and divide it by 2:
5,385,413 ÷ 2 = 2,692,706.5
If the quotient is a whole number, then 2 and 2,692,706.5 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 | 5,385,413 | |
| -1 | -5,385,413 |
Now, we try dividing 5,385,413 by 3:
5,385,413 ÷ 3 = 1,795,137.6667
If the quotient is a whole number, then 3 and 1,795,137.6667 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 | 5,385,413 | |
| -1 | -5,385,413 |
Let's try dividing by 4:
5,385,413 ÷ 4 = 1,346,353.25
If the quotient is a whole number, then 4 and 1,346,353.25 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 | 5,385,413 | |
| -1 | 5,385,413 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 31 | 187 | 341 | 527 | 929 | 5,797 | 10,219 | 15,793 | 28,799 | 173,723 | 316,789 | 489,583 | 5,385,413 |
| -1 | -11 | -17 | -31 | -187 | -341 | -527 | -929 | -5,797 | -10,219 | -15,793 | -28,799 | -173,723 | -316,789 | -489,583 | -5,385,413 |
