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 1,166,905, 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 | 1,166,905 | |
| -1 | -1,166,905 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,166,905.
Example:
1 x 1,166,905 = 1,166,905
and
-1 x -1,166,905 = 1,166,905
Notice both answers equal 1,166,905
With that explanation out of the way, let's continue. Next, we take the number 1,166,905 and divide it by 2:
1,166,905 ÷ 2 = 583,452.5
If the quotient is a whole number, then 2 and 583,452.5 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 | 1,166,905 | |
| -1 | -1,166,905 |
Now, we try dividing 1,166,905 by 3:
1,166,905 ÷ 3 = 388,968.3333
If the quotient is a whole number, then 3 and 388,968.3333 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 | 1,166,905 | |
| -1 | -1,166,905 |
Let's try dividing by 4:
1,166,905 ÷ 4 = 291,726.25
If the quotient is a whole number, then 4 and 291,726.25 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 | 1,166,905 | |
| -1 | 1,166,905 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 73 | 115 | 139 | 365 | 695 | 1,679 | 3,197 | 8,395 | 10,147 | 15,985 | 50,735 | 233,381 | 1,166,905 |
| -1 | -5 | -23 | -73 | -115 | -139 | -365 | -695 | -1,679 | -3,197 | -8,395 | -10,147 | -15,985 | -50,735 | -233,381 | -1,166,905 |
