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 1,511,653, 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 | 1,511,653 | |
| -1 | -1,511,653 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,511,653.
Example:
1 x 1,511,653 = 1,511,653
and
-1 x -1,511,653 = 1,511,653
Notice both answers equal 1,511,653
With that explanation out of the way, let's continue. Next, we take the number 1,511,653 and divide it by 2:
1,511,653 ÷ 2 = 755,826.5
If the quotient is a whole number, then 2 and 755,826.5 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 | 1,511,653 | |
| -1 | -1,511,653 |
Now, we try dividing 1,511,653 by 3:
1,511,653 ÷ 3 = 503,884.3333
If the quotient is a whole number, then 3 and 503,884.3333 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 | 1,511,653 | |
| -1 | -1,511,653 |
Let's try dividing by 4:
1,511,653 ÷ 4 = 377,913.25
If the quotient is a whole number, then 4 and 377,913.25 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 | 1,511,653 | |
| -1 | 1,511,653 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 31 | 121 | 143 | 341 | 403 | 961 | 1,573 | 3,751 | 4,433 | 10,571 | 12,493 | 48,763 | 116,281 | 137,423 | 1,511,653 |
| -1 | -11 | -13 | -31 | -121 | -143 | -341 | -403 | -961 | -1,573 | -3,751 | -4,433 | -10,571 | -12,493 | -48,763 | -116,281 | -137,423 | -1,511,653 |
