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 5,099,155, 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 | 5,099,155 | |
| -1 | -5,099,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,099,155.
Example:
1 x 5,099,155 = 5,099,155
and
-1 x -5,099,155 = 5,099,155
Notice both answers equal 5,099,155
With that explanation out of the way, let's continue. Next, we take the number 5,099,155 and divide it by 2:
5,099,155 ÷ 2 = 2,549,577.5
If the quotient is a whole number, then 2 and 2,549,577.5 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 | 5,099,155 | |
| -1 | -5,099,155 |
Now, we try dividing 5,099,155 by 3:
5,099,155 ÷ 3 = 1,699,718.3333
If the quotient is a whole number, then 3 and 1,699,718.3333 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 | 5,099,155 | |
| -1 | -5,099,155 |
Let's try dividing by 4:
5,099,155 ÷ 4 = 1,274,788.75
If the quotient is a whole number, then 4 and 1,274,788.75 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 | 5,099,155 | |
| -1 | 5,099,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 43 | 185 | 215 | 641 | 1,591 | 3,205 | 7,955 | 23,717 | 27,563 | 118,585 | 137,815 | 1,019,831 | 5,099,155 |
| -1 | -5 | -37 | -43 | -185 | -215 | -641 | -1,591 | -3,205 | -7,955 | -23,717 | -27,563 | -118,585 | -137,815 | -1,019,831 | -5,099,155 |
