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 1,489,315, 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 | 1,489,315 | |
| -1 | -1,489,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,489,315.
Example:
1 x 1,489,315 = 1,489,315
and
-1 x -1,489,315 = 1,489,315
Notice both answers equal 1,489,315
With that explanation out of the way, let's continue. Next, we take the number 1,489,315 and divide it by 2:
1,489,315 ÷ 2 = 744,657.5
If the quotient is a whole number, then 2 and 744,657.5 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 | 1,489,315 | |
| -1 | -1,489,315 |
Now, we try dividing 1,489,315 by 3:
1,489,315 ÷ 3 = 496,438.3333
If the quotient is a whole number, then 3 and 496,438.3333 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 | 1,489,315 | |
| -1 | -1,489,315 |
Let's try dividing by 4:
1,489,315 ÷ 4 = 372,328.75
If the quotient is a whole number, then 4 and 372,328.75 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 | 1,489,315 | |
| -1 | 1,489,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 61 | 95 | 257 | 305 | 1,159 | 1,285 | 4,883 | 5,795 | 15,677 | 24,415 | 78,385 | 297,863 | 1,489,315 |
| -1 | -5 | -19 | -61 | -95 | -257 | -305 | -1,159 | -1,285 | -4,883 | -5,795 | -15,677 | -24,415 | -78,385 | -297,863 | -1,489,315 |
