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 13,679,435, 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 | 13,679,435 | |
| -1 | -13,679,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,679,435.
Example:
1 x 13,679,435 = 13,679,435
and
-1 x -13,679,435 = 13,679,435
Notice both answers equal 13,679,435
With that explanation out of the way, let's continue. Next, we take the number 13,679,435 and divide it by 2:
13,679,435 ÷ 2 = 6,839,717.5
If the quotient is a whole number, then 2 and 6,839,717.5 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 | 13,679,435 | |
| -1 | -13,679,435 |
Now, we try dividing 13,679,435 by 3:
13,679,435 ÷ 3 = 4,559,811.6667
If the quotient is a whole number, then 3 and 4,559,811.6667 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 | 13,679,435 | |
| -1 | -13,679,435 |
Let's try dividing by 4:
13,679,435 ÷ 4 = 3,419,858.75
If the quotient is a whole number, then 4 and 3,419,858.75 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 | 13,679,435 | |
| -1 | 13,679,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 35,531 | 177,655 | 248,717 | 390,841 | 1,243,585 | 1,954,205 | 2,735,887 | 13,679,435 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -35,531 | -177,655 | -248,717 | -390,841 | -1,243,585 | -1,954,205 | -2,735,887 | -13,679,435 |
