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 1,190,105, 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 | 1,190,105 | |
| -1 | -1,190,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,190,105.
Example:
1 x 1,190,105 = 1,190,105
and
-1 x -1,190,105 = 1,190,105
Notice both answers equal 1,190,105
With that explanation out of the way, let's continue. Next, we take the number 1,190,105 and divide it by 2:
1,190,105 ÷ 2 = 595,052.5
If the quotient is a whole number, then 2 and 595,052.5 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 | 1,190,105 | |
| -1 | -1,190,105 |
Now, we try dividing 1,190,105 by 3:
1,190,105 ÷ 3 = 396,701.6667
If the quotient is a whole number, then 3 and 396,701.6667 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 | 1,190,105 | |
| -1 | -1,190,105 |
Let's try dividing by 4:
1,190,105 ÷ 4 = 297,526.25
If the quotient is a whole number, then 4 and 297,526.25 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 | 1,190,105 | |
| -1 | 1,190,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 37 | 185 | 259 | 919 | 1,295 | 4,595 | 6,433 | 32,165 | 34,003 | 170,015 | 238,021 | 1,190,105 |
| -1 | -5 | -7 | -35 | -37 | -185 | -259 | -919 | -1,295 | -4,595 | -6,433 | -32,165 | -34,003 | -170,015 | -238,021 | -1,190,105 |
