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 1,051,115, 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 | 1,051,115 | |
| -1 | -1,051,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,051,115.
Example:
1 x 1,051,115 = 1,051,115
and
-1 x -1,051,115 = 1,051,115
Notice both answers equal 1,051,115
With that explanation out of the way, let's continue. Next, we take the number 1,051,115 and divide it by 2:
1,051,115 ÷ 2 = 525,557.5
If the quotient is a whole number, then 2 and 525,557.5 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 | 1,051,115 | |
| -1 | -1,051,115 |
Now, we try dividing 1,051,115 by 3:
1,051,115 ÷ 3 = 350,371.6667
If the quotient is a whole number, then 3 and 350,371.6667 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 | 1,051,115 | |
| -1 | -1,051,115 |
Let's try dividing by 4:
1,051,115 ÷ 4 = 262,778.75
If the quotient is a whole number, then 4 and 262,778.75 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 | 1,051,115 | |
| -1 | 1,051,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 103 | 157 | 515 | 785 | 1,339 | 2,041 | 6,695 | 10,205 | 16,171 | 80,855 | 210,223 | 1,051,115 |
| -1 | -5 | -13 | -65 | -103 | -157 | -515 | -785 | -1,339 | -2,041 | -6,695 | -10,205 | -16,171 | -80,855 | -210,223 | -1,051,115 |
