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 1,050,215, 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 | 1,050,215 | |
| -1 | -1,050,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,050,215.
Example:
1 x 1,050,215 = 1,050,215
and
-1 x -1,050,215 = 1,050,215
Notice both answers equal 1,050,215
With that explanation out of the way, let's continue. Next, we take the number 1,050,215 and divide it by 2:
1,050,215 ÷ 2 = 525,107.5
If the quotient is a whole number, then 2 and 525,107.5 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 | 1,050,215 | |
| -1 | -1,050,215 |
Now, we try dividing 1,050,215 by 3:
1,050,215 ÷ 3 = 350,071.6667
If the quotient is a whole number, then 3 and 350,071.6667 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 | 1,050,215 | |
| -1 | -1,050,215 |
Let's try dividing by 4:
1,050,215 ÷ 4 = 262,553.75
If the quotient is a whole number, then 4 and 262,553.75 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 | 1,050,215 | |
| -1 | 1,050,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 47 | 109 | 205 | 235 | 545 | 1,927 | 4,469 | 5,123 | 9,635 | 22,345 | 25,615 | 210,043 | 1,050,215 |
| -1 | -5 | -41 | -47 | -109 | -205 | -235 | -545 | -1,927 | -4,469 | -5,123 | -9,635 | -22,345 | -25,615 | -210,043 | -1,050,215 |
