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 1,286,495, 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 | 1,286,495 | |
| -1 | -1,286,495 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,286,495.
Example:
1 x 1,286,495 = 1,286,495
and
-1 x -1,286,495 = 1,286,495
Notice both answers equal 1,286,495
With that explanation out of the way, let's continue. Next, we take the number 1,286,495 and divide it by 2:
1,286,495 ÷ 2 = 643,247.5
If the quotient is a whole number, then 2 and 643,247.5 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 | 1,286,495 | |
| -1 | -1,286,495 |
Now, we try dividing 1,286,495 by 3:
1,286,495 ÷ 3 = 428,831.6667
If the quotient is a whole number, then 3 and 428,831.6667 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 | 1,286,495 | |
| -1 | -1,286,495 |
Let's try dividing by 4:
1,286,495 ÷ 4 = 321,623.75
If the quotient is a whole number, then 4 and 321,623.75 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 | 1,286,495 | |
| -1 | 1,286,495 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 59 | 89 | 245 | 295 | 413 | 445 | 623 | 2,065 | 2,891 | 3,115 | 4,361 | 5,251 | 14,455 | 21,805 | 26,255 | 36,757 | 183,785 | 257,299 | 1,286,495 |
| -1 | -5 | -7 | -35 | -49 | -59 | -89 | -245 | -295 | -413 | -445 | -623 | -2,065 | -2,891 | -3,115 | -4,361 | -5,251 | -14,455 | -21,805 | -26,255 | -36,757 | -183,785 | -257,299 | -1,286,495 |
