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 13,424,635, 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 | 13,424,635 | |
| -1 | -13,424,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,424,635.
Example:
1 x 13,424,635 = 13,424,635
and
-1 x -13,424,635 = 13,424,635
Notice both answers equal 13,424,635
With that explanation out of the way, let's continue. Next, we take the number 13,424,635 and divide it by 2:
13,424,635 ÷ 2 = 6,712,317.5
If the quotient is a whole number, then 2 and 6,712,317.5 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 | 13,424,635 | |
| -1 | -13,424,635 |
Now, we try dividing 13,424,635 by 3:
13,424,635 ÷ 3 = 4,474,878.3333
If the quotient is a whole number, then 3 and 4,474,878.3333 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 | 13,424,635 | |
| -1 | -13,424,635 |
Let's try dividing by 4:
13,424,635 ÷ 4 = 3,356,158.75
If the quotient is a whole number, then 4 and 3,356,158.75 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 | 13,424,635 | |
| -1 | 13,424,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 53 | 265 | 371 | 1,855 | 7,237 | 36,185 | 50,659 | 253,295 | 383,561 | 1,917,805 | 2,684,927 | 13,424,635 |
| -1 | -5 | -7 | -35 | -53 | -265 | -371 | -1,855 | -7,237 | -36,185 | -50,659 | -253,295 | -383,561 | -1,917,805 | -2,684,927 | -13,424,635 |
