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 1,015,495, 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 | 1,015,495 | |
| -1 | -1,015,495 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,015,495.
Example:
1 x 1,015,495 = 1,015,495
and
-1 x -1,015,495 = 1,015,495
Notice both answers equal 1,015,495
With that explanation out of the way, let's continue. Next, we take the number 1,015,495 and divide it by 2:
1,015,495 ÷ 2 = 507,747.5
If the quotient is a whole number, then 2 and 507,747.5 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 | 1,015,495 | |
| -1 | -1,015,495 |
Now, we try dividing 1,015,495 by 3:
1,015,495 ÷ 3 = 338,498.3333
If the quotient is a whole number, then 3 and 338,498.3333 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 | 1,015,495 | |
| -1 | -1,015,495 |
Let's try dividing by 4:
1,015,495 ÷ 4 = 253,873.75
If the quotient is a whole number, then 4 and 253,873.75 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 | 1,015,495 | |
| -1 | 1,015,495 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 919 | 1,105 | 4,595 | 11,947 | 15,623 | 59,735 | 78,115 | 203,099 | 1,015,495 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -919 | -1,105 | -4,595 | -11,947 | -15,623 | -59,735 | -78,115 | -203,099 | -1,015,495 |
