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 13,046,005, 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 | 13,046,005 | |
| -1 | -13,046,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,046,005.
Example:
1 x 13,046,005 = 13,046,005
and
-1 x -13,046,005 = 13,046,005
Notice both answers equal 13,046,005
With that explanation out of the way, let's continue. Next, we take the number 13,046,005 and divide it by 2:
13,046,005 ÷ 2 = 6,523,002.5
If the quotient is a whole number, then 2 and 6,523,002.5 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 | 13,046,005 | |
| -1 | -13,046,005 |
Now, we try dividing 13,046,005 by 3:
13,046,005 ÷ 3 = 4,348,668.3333
If the quotient is a whole number, then 3 and 4,348,668.3333 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 | 13,046,005 | |
| -1 | -13,046,005 |
Let's try dividing by 4:
13,046,005 ÷ 4 = 3,261,501.25
If the quotient is a whole number, then 4 and 3,261,501.25 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 | 13,046,005 | |
| -1 | 13,046,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 343 | 1,715 | 7,607 | 38,035 | 53,249 | 266,245 | 372,743 | 1,863,715 | 2,609,201 | 13,046,005 |
| -1 | -5 | -7 | -35 | -49 | -245 | -343 | -1,715 | -7,607 | -38,035 | -53,249 | -266,245 | -372,743 | -1,863,715 | -2,609,201 | -13,046,005 |
