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 5,787,155, 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 | 5,787,155 | |
| -1 | -5,787,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,787,155.
Example:
1 x 5,787,155 = 5,787,155
and
-1 x -5,787,155 = 5,787,155
Notice both answers equal 5,787,155
With that explanation out of the way, let's continue. Next, we take the number 5,787,155 and divide it by 2:
5,787,155 ÷ 2 = 2,893,577.5
If the quotient is a whole number, then 2 and 2,893,577.5 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 | 5,787,155 | |
| -1 | -5,787,155 |
Now, we try dividing 5,787,155 by 3:
5,787,155 ÷ 3 = 1,929,051.6667
If the quotient is a whole number, then 3 and 1,929,051.6667 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 | 5,787,155 | |
| -1 | -5,787,155 |
Let's try dividing by 4:
5,787,155 ÷ 4 = 1,446,788.75
If the quotient is a whole number, then 4 and 1,446,788.75 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 | 5,787,155 | |
| -1 | 5,787,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 43 | 55 | 215 | 473 | 2,365 | 2,447 | 12,235 | 26,917 | 105,221 | 134,585 | 526,105 | 1,157,431 | 5,787,155 |
| -1 | -5 | -11 | -43 | -55 | -215 | -473 | -2,365 | -2,447 | -12,235 | -26,917 | -105,221 | -134,585 | -526,105 | -1,157,431 | -5,787,155 |
