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 1,510,229, 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 | 1,510,229 | |
| -1 | -1,510,229 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,510,229.
Example:
1 x 1,510,229 = 1,510,229
and
-1 x -1,510,229 = 1,510,229
Notice both answers equal 1,510,229
With that explanation out of the way, let's continue. Next, we take the number 1,510,229 and divide it by 2:
1,510,229 ÷ 2 = 755,114.5
If the quotient is a whole number, then 2 and 755,114.5 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 | 1,510,229 | |
| -1 | -1,510,229 |
Now, we try dividing 1,510,229 by 3:
1,510,229 ÷ 3 = 503,409.6667
If the quotient is a whole number, then 3 and 503,409.6667 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 | 1,510,229 | |
| -1 | -1,510,229 |
Let's try dividing by 4:
1,510,229 ÷ 4 = 377,557.25
If the quotient is a whole number, then 4 and 377,557.25 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 | 1,510,229 | |
| -1 | 1,510,229 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 37 | 49 | 119 | 259 | 343 | 629 | 833 | 1,813 | 2,401 | 4,403 | 5,831 | 12,691 | 30,821 | 40,817 | 88,837 | 215,747 | 1,510,229 |
| -1 | -7 | -17 | -37 | -49 | -119 | -259 | -343 | -629 | -833 | -1,813 | -2,401 | -4,403 | -5,831 | -12,691 | -30,821 | -40,817 | -88,837 | -215,747 | -1,510,229 |
