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 4,518,185, 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 | 4,518,185 | |
| -1 | -4,518,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,518,185.
Example:
1 x 4,518,185 = 4,518,185
and
-1 x -4,518,185 = 4,518,185
Notice both answers equal 4,518,185
With that explanation out of the way, let's continue. Next, we take the number 4,518,185 and divide it by 2:
4,518,185 ÷ 2 = 2,259,092.5
If the quotient is a whole number, then 2 and 2,259,092.5 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 | 4,518,185 | |
| -1 | -4,518,185 |
Now, we try dividing 4,518,185 by 3:
4,518,185 ÷ 3 = 1,506,061.6667
If the quotient is a whole number, then 3 and 1,506,061.6667 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 | 4,518,185 | |
| -1 | -4,518,185 |
Let's try dividing by 4:
4,518,185 ÷ 4 = 1,129,546.25
If the quotient is a whole number, then 4 and 1,129,546.25 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 | 4,518,185 | |
| -1 | 4,518,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 167 | 773 | 835 | 1,169 | 3,865 | 5,411 | 5,845 | 27,055 | 129,091 | 645,455 | 903,637 | 4,518,185 |
| -1 | -5 | -7 | -35 | -167 | -773 | -835 | -1,169 | -3,865 | -5,411 | -5,845 | -27,055 | -129,091 | -645,455 | -903,637 | -4,518,185 |
