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 1,354,045, 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 | 1,354,045 | |
| -1 | -1,354,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,354,045.
Example:
1 x 1,354,045 = 1,354,045
and
-1 x -1,354,045 = 1,354,045
Notice both answers equal 1,354,045
With that explanation out of the way, let's continue. Next, we take the number 1,354,045 and divide it by 2:
1,354,045 ÷ 2 = 677,022.5
If the quotient is a whole number, then 2 and 677,022.5 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 | 1,354,045 | |
| -1 | -1,354,045 |
Now, we try dividing 1,354,045 by 3:
1,354,045 ÷ 3 = 451,348.3333
If the quotient is a whole number, then 3 and 451,348.3333 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 | 1,354,045 | |
| -1 | -1,354,045 |
Let's try dividing by 4:
1,354,045 ÷ 4 = 338,511.25
If the quotient is a whole number, then 4 and 338,511.25 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 | 1,354,045 | |
| -1 | 1,354,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 3,517 | 17,585 | 24,619 | 38,687 | 123,095 | 193,435 | 270,809 | 1,354,045 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -3,517 | -17,585 | -24,619 | -38,687 | -123,095 | -193,435 | -270,809 | -1,354,045 |
