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 4,518,941, 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 | 4,518,941 | |
| -1 | -4,518,941 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,518,941.
Example:
1 x 4,518,941 = 4,518,941
and
-1 x -4,518,941 = 4,518,941
Notice both answers equal 4,518,941
With that explanation out of the way, let's continue. Next, we take the number 4,518,941 and divide it by 2:
4,518,941 ÷ 2 = 2,259,470.5
If the quotient is a whole number, then 2 and 2,259,470.5 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 | 4,518,941 | |
| -1 | -4,518,941 |
Now, we try dividing 4,518,941 by 3:
4,518,941 ÷ 3 = 1,506,313.6667
If the quotient is a whole number, then 3 and 1,506,313.6667 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 | 4,518,941 | |
| -1 | -4,518,941 |
Let's try dividing by 4:
4,518,941 ÷ 4 = 1,129,735.25
If the quotient is a whole number, then 4 and 1,129,735.25 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 | 4,518,941 | |
| -1 | 4,518,941 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 61 | 133 | 427 | 557 | 1,159 | 3,899 | 8,113 | 10,583 | 33,977 | 74,081 | 237,839 | 645,563 | 4,518,941 |
| -1 | -7 | -19 | -61 | -133 | -427 | -557 | -1,159 | -3,899 | -8,113 | -10,583 | -33,977 | -74,081 | -237,839 | -645,563 | -4,518,941 |
