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 1,840,111, 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 | 1,840,111 | |
| -1 | -1,840,111 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,840,111.
Example:
1 x 1,840,111 = 1,840,111
and
-1 x -1,840,111 = 1,840,111
Notice both answers equal 1,840,111
With that explanation out of the way, let's continue. Next, we take the number 1,840,111 and divide it by 2:
1,840,111 ÷ 2 = 920,055.5
If the quotient is a whole number, then 2 and 920,055.5 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 | 1,840,111 | |
| -1 | -1,840,111 |
Now, we try dividing 1,840,111 by 3:
1,840,111 ÷ 3 = 613,370.3333
If the quotient is a whole number, then 3 and 613,370.3333 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 | 1,840,111 | |
| -1 | -1,840,111 |
Let's try dividing by 4:
1,840,111 ÷ 4 = 460,027.75
If the quotient is a whole number, then 4 and 460,027.75 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 | 1,840,111 | |
| -1 | 1,840,111 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 73 | 91 | 277 | 511 | 949 | 1,939 | 3,601 | 6,643 | 20,221 | 25,207 | 141,547 | 262,873 | 1,840,111 |
| -1 | -7 | -13 | -73 | -91 | -277 | -511 | -949 | -1,939 | -3,601 | -6,643 | -20,221 | -25,207 | -141,547 | -262,873 | -1,840,111 |
