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 12,704,263, 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 | 12,704,263 | |
| -1 | -12,704,263 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,704,263.
Example:
1 x 12,704,263 = 12,704,263
and
-1 x -12,704,263 = 12,704,263
Notice both answers equal 12,704,263
With that explanation out of the way, let's continue. Next, we take the number 12,704,263 and divide it by 2:
12,704,263 ÷ 2 = 6,352,131.5
If the quotient is a whole number, then 2 and 6,352,131.5 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 | 12,704,263 | |
| -1 | -12,704,263 |
Now, we try dividing 12,704,263 by 3:
12,704,263 ÷ 3 = 4,234,754.3333
If the quotient is a whole number, then 3 and 4,234,754.3333 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 | 12,704,263 | |
| -1 | -12,704,263 |
Let's try dividing by 4:
12,704,263 ÷ 4 = 3,176,065.75
If the quotient is a whole number, then 4 and 3,176,065.75 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 | 12,704,263 | |
| -1 | 12,704,263 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 73 | 143 | 803 | 949 | 1,217 | 10,439 | 13,387 | 15,821 | 88,841 | 174,031 | 977,251 | 1,154,933 | 12,704,263 |
| -1 | -11 | -13 | -73 | -143 | -803 | -949 | -1,217 | -10,439 | -13,387 | -15,821 | -88,841 | -174,031 | -977,251 | -1,154,933 | -12,704,263 |
