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 1,184,897, 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 | 1,184,897 | |
| -1 | -1,184,897 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,184,897.
Example:
1 x 1,184,897 = 1,184,897
and
-1 x -1,184,897 = 1,184,897
Notice both answers equal 1,184,897
With that explanation out of the way, let's continue. Next, we take the number 1,184,897 and divide it by 2:
1,184,897 ÷ 2 = 592,448.5
If the quotient is a whole number, then 2 and 592,448.5 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 | 1,184,897 | |
| -1 | -1,184,897 |
Now, we try dividing 1,184,897 by 3:
1,184,897 ÷ 3 = 394,965.6667
If the quotient is a whole number, then 3 and 394,965.6667 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 | 1,184,897 | |
| -1 | -1,184,897 |
Let's try dividing by 4:
1,184,897 ÷ 4 = 296,224.25
If the quotient is a whole number, then 4 and 296,224.25 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 | 1,184,897 | |
| -1 | 1,184,897 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 59 | 133 | 151 | 413 | 1,057 | 1,121 | 2,869 | 7,847 | 8,909 | 20,083 | 62,363 | 169,271 | 1,184,897 |
| -1 | -7 | -19 | -59 | -133 | -151 | -413 | -1,057 | -1,121 | -2,869 | -7,847 | -8,909 | -20,083 | -62,363 | -169,271 | -1,184,897 |
