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 5,155,579, 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 | 5,155,579 | |
| -1 | -5,155,579 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,155,579.
Example:
1 x 5,155,579 = 5,155,579
and
-1 x -5,155,579 = 5,155,579
Notice both answers equal 5,155,579
With that explanation out of the way, let's continue. Next, we take the number 5,155,579 and divide it by 2:
5,155,579 ÷ 2 = 2,577,789.5
If the quotient is a whole number, then 2 and 2,577,789.5 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 | 5,155,579 | |
| -1 | -5,155,579 |
Now, we try dividing 5,155,579 by 3:
5,155,579 ÷ 3 = 1,718,526.3333
If the quotient is a whole number, then 3 and 1,718,526.3333 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 | 5,155,579 | |
| -1 | -5,155,579 |
Let's try dividing by 4:
5,155,579 ÷ 4 = 1,288,894.75
If the quotient is a whole number, then 4 and 1,288,894.75 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 | 5,155,579 | |
| -1 | 5,155,579 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 31 | 143 | 341 | 403 | 1,163 | 4,433 | 12,793 | 15,119 | 36,053 | 166,309 | 396,583 | 468,689 | 5,155,579 |
| -1 | -11 | -13 | -31 | -143 | -341 | -403 | -1,163 | -4,433 | -12,793 | -15,119 | -36,053 | -166,309 | -396,583 | -468,689 | -5,155,579 |
