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 1,549,849, 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 | 1,549,849 | |
| -1 | -1,549,849 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,549,849.
Example:
1 x 1,549,849 = 1,549,849
and
-1 x -1,549,849 = 1,549,849
Notice both answers equal 1,549,849
With that explanation out of the way, let's continue. Next, we take the number 1,549,849 and divide it by 2:
1,549,849 ÷ 2 = 774,924.5
If the quotient is a whole number, then 2 and 774,924.5 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 | 1,549,849 | |
| -1 | -1,549,849 |
Now, we try dividing 1,549,849 by 3:
1,549,849 ÷ 3 = 516,616.3333
If the quotient is a whole number, then 3 and 516,616.3333 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 | 1,549,849 | |
| -1 | -1,549,849 |
Let's try dividing by 4:
1,549,849 ÷ 4 = 387,462.25
If the quotient is a whole number, then 4 and 387,462.25 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 | 1,549,849 | |
| -1 | 1,549,849 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 43 | 133 | 271 | 301 | 817 | 1,897 | 5,149 | 5,719 | 11,653 | 36,043 | 81,571 | 221,407 | 1,549,849 |
| -1 | -7 | -19 | -43 | -133 | -271 | -301 | -817 | -1,897 | -5,149 | -5,719 | -11,653 | -36,043 | -81,571 | -221,407 | -1,549,849 |
