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 12,854,303, 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 | 12,854,303 | |
| -1 | -12,854,303 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,854,303.
Example:
1 x 12,854,303 = 12,854,303
and
-1 x -12,854,303 = 12,854,303
Notice both answers equal 12,854,303
With that explanation out of the way, let's continue. Next, we take the number 12,854,303 and divide it by 2:
12,854,303 ÷ 2 = 6,427,151.5
If the quotient is a whole number, then 2 and 6,427,151.5 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 | 12,854,303 | |
| -1 | -12,854,303 |
Now, we try dividing 12,854,303 by 3:
12,854,303 ÷ 3 = 4,284,767.6667
If the quotient is a whole number, then 3 and 4,284,767.6667 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 | 12,854,303 | |
| -1 | -12,854,303 |
Let's try dividing by 4:
12,854,303 ÷ 4 = 3,213,575.75
If the quotient is a whole number, then 4 and 3,213,575.75 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 | 12,854,303 | |
| -1 | 12,854,303 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 139 | 973 | 1,201 | 1,529 | 8,407 | 10,703 | 13,211 | 92,477 | 166,939 | 1,168,573 | 1,836,329 | 12,854,303 |
| -1 | -7 | -11 | -77 | -139 | -973 | -1,201 | -1,529 | -8,407 | -10,703 | -13,211 | -92,477 | -166,939 | -1,168,573 | -1,836,329 | -12,854,303 |
