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 1,500,415, 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 | 1,500,415 | |
| -1 | -1,500,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,500,415.
Example:
1 x 1,500,415 = 1,500,415
and
-1 x -1,500,415 = 1,500,415
Notice both answers equal 1,500,415
With that explanation out of the way, let's continue. Next, we take the number 1,500,415 and divide it by 2:
1,500,415 ÷ 2 = 750,207.5
If the quotient is a whole number, then 2 and 750,207.5 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 | 1,500,415 | |
| -1 | -1,500,415 |
Now, we try dividing 1,500,415 by 3:
1,500,415 ÷ 3 = 500,138.3333
If the quotient is a whole number, then 3 and 500,138.3333 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 | 1,500,415 | |
| -1 | -1,500,415 |
Let's try dividing by 4:
1,500,415 ÷ 4 = 375,103.75
If the quotient is a whole number, then 4 and 375,103.75 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 | 1,500,415 | |
| -1 | 1,500,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 163 | 263 | 815 | 1,141 | 1,315 | 1,841 | 5,705 | 9,205 | 42,869 | 214,345 | 300,083 | 1,500,415 |
| -1 | -5 | -7 | -35 | -163 | -263 | -815 | -1,141 | -1,315 | -1,841 | -5,705 | -9,205 | -42,869 | -214,345 | -300,083 | -1,500,415 |
