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 1,521,551, 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 | 1,521,551 | |
| -1 | -1,521,551 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,521,551.
Example:
1 x 1,521,551 = 1,521,551
and
-1 x -1,521,551 = 1,521,551
Notice both answers equal 1,521,551
With that explanation out of the way, let's continue. Next, we take the number 1,521,551 and divide it by 2:
1,521,551 ÷ 2 = 760,775.5
If the quotient is a whole number, then 2 and 760,775.5 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 | 1,521,551 | |
| -1 | -1,521,551 |
Now, we try dividing 1,521,551 by 3:
1,521,551 ÷ 3 = 507,183.6667
If the quotient is a whole number, then 3 and 507,183.6667 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 | 1,521,551 | |
| -1 | -1,521,551 |
Let's try dividing by 4:
1,521,551 ÷ 4 = 380,387.75
If the quotient is a whole number, then 4 and 380,387.75 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 | 1,521,551 | |
| -1 | 1,521,551 |
If you did it right, you will end up with this table:
| 1 | 17 | 37 | 41 | 59 | 629 | 697 | 1,003 | 1,517 | 2,183 | 2,419 | 25,789 | 37,111 | 41,123 | 89,503 | 1,521,551 |
| -1 | -17 | -37 | -41 | -59 | -629 | -697 | -1,003 | -1,517 | -2,183 | -2,419 | -25,789 | -37,111 | -41,123 | -89,503 | -1,521,551 |
