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 12,650,029, 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 | 12,650,029 | |
| -1 | -12,650,029 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,650,029.
Example:
1 x 12,650,029 = 12,650,029
and
-1 x -12,650,029 = 12,650,029
Notice both answers equal 12,650,029
With that explanation out of the way, let's continue. Next, we take the number 12,650,029 and divide it by 2:
12,650,029 ÷ 2 = 6,325,014.5
If the quotient is a whole number, then 2 and 6,325,014.5 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 | 12,650,029 | |
| -1 | -12,650,029 |
Now, we try dividing 12,650,029 by 3:
12,650,029 ÷ 3 = 4,216,676.3333
If the quotient is a whole number, then 3 and 4,216,676.3333 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 | 12,650,029 | |
| -1 | -12,650,029 |
Let's try dividing by 4:
12,650,029 ÷ 4 = 3,162,507.25
If the quotient is a whole number, then 4 and 3,162,507.25 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 | 12,650,029 | |
| -1 | 12,650,029 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 227 | 419 | 1,589 | 2,933 | 4,313 | 7,961 | 30,191 | 55,727 | 95,113 | 665,791 | 1,807,147 | 12,650,029 |
| -1 | -7 | -19 | -133 | -227 | -419 | -1,589 | -2,933 | -4,313 | -7,961 | -30,191 | -55,727 | -95,113 | -665,791 | -1,807,147 | -12,650,029 |
