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 1,411,267, 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 | 1,411,267 | |
| -1 | -1,411,267 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,411,267.
Example:
1 x 1,411,267 = 1,411,267
and
-1 x -1,411,267 = 1,411,267
Notice both answers equal 1,411,267
With that explanation out of the way, let's continue. Next, we take the number 1,411,267 and divide it by 2:
1,411,267 ÷ 2 = 705,633.5
If the quotient is a whole number, then 2 and 705,633.5 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 | 1,411,267 | |
| -1 | -1,411,267 |
Now, we try dividing 1,411,267 by 3:
1,411,267 ÷ 3 = 470,422.3333
If the quotient is a whole number, then 3 and 470,422.3333 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 | 1,411,267 | |
| -1 | -1,411,267 |
Let's try dividing by 4:
1,411,267 ÷ 4 = 352,816.75
If the quotient is a whole number, then 4 and 352,816.75 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 | 1,411,267 | |
| -1 | 1,411,267 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 71 | 139 | 143 | 781 | 923 | 1,529 | 1,807 | 9,869 | 10,153 | 19,877 | 108,559 | 128,297 | 1,411,267 |
| -1 | -11 | -13 | -71 | -139 | -143 | -781 | -923 | -1,529 | -1,807 | -9,869 | -10,153 | -19,877 | -108,559 | -128,297 | -1,411,267 |
