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 13,430,417, 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 | 13,430,417 | |
| -1 | -13,430,417 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,430,417.
Example:
1 x 13,430,417 = 13,430,417
and
-1 x -13,430,417 = 13,430,417
Notice both answers equal 13,430,417
With that explanation out of the way, let's continue. Next, we take the number 13,430,417 and divide it by 2:
13,430,417 ÷ 2 = 6,715,208.5
If the quotient is a whole number, then 2 and 6,715,208.5 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 | 13,430,417 | |
| -1 | -13,430,417 |
Now, we try dividing 13,430,417 by 3:
13,430,417 ÷ 3 = 4,476,805.6667
If the quotient is a whole number, then 3 and 4,476,805.6667 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 | 13,430,417 | |
| -1 | -13,430,417 |
Let's try dividing by 4:
13,430,417 ÷ 4 = 3,357,604.25
If the quotient is a whole number, then 4 and 3,357,604.25 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 | 13,430,417 | |
| -1 | 13,430,417 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 1,001 | 13,417 | 93,919 | 147,587 | 174,421 | 1,033,109 | 1,220,947 | 1,918,631 | 13,430,417 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -1,001 | -13,417 | -93,919 | -147,587 | -174,421 | -1,033,109 | -1,220,947 | -1,918,631 | -13,430,417 |
