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 1,386,469, 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 | 1,386,469 | |
| -1 | -1,386,469 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,386,469.
Example:
1 x 1,386,469 = 1,386,469
and
-1 x -1,386,469 = 1,386,469
Notice both answers equal 1,386,469
With that explanation out of the way, let's continue. Next, we take the number 1,386,469 and divide it by 2:
1,386,469 ÷ 2 = 693,234.5
If the quotient is a whole number, then 2 and 693,234.5 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 | 1,386,469 | |
| -1 | -1,386,469 |
Now, we try dividing 1,386,469 by 3:
1,386,469 ÷ 3 = 462,156.3333
If the quotient is a whole number, then 3 and 462,156.3333 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 | 1,386,469 | |
| -1 | -1,386,469 |
Let's try dividing by 4:
1,386,469 ÷ 4 = 346,617.25
If the quotient is a whole number, then 4 and 346,617.25 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 | 1,386,469 | |
| -1 | 1,386,469 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 61 | 119 | 191 | 427 | 1,037 | 1,337 | 3,247 | 7,259 | 11,651 | 22,729 | 81,557 | 198,067 | 1,386,469 |
| -1 | -7 | -17 | -61 | -119 | -191 | -427 | -1,037 | -1,337 | -3,247 | -7,259 | -11,651 | -22,729 | -81,557 | -198,067 | -1,386,469 |
