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 13,762,511, 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 | 13,762,511 | |
| -1 | -13,762,511 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,762,511.
Example:
1 x 13,762,511 = 13,762,511
and
-1 x -13,762,511 = 13,762,511
Notice both answers equal 13,762,511
With that explanation out of the way, let's continue. Next, we take the number 13,762,511 and divide it by 2:
13,762,511 ÷ 2 = 6,881,255.5
If the quotient is a whole number, then 2 and 6,881,255.5 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 | 13,762,511 | |
| -1 | -13,762,511 |
Now, we try dividing 13,762,511 by 3:
13,762,511 ÷ 3 = 4,587,503.6667
If the quotient is a whole number, then 3 and 4,587,503.6667 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 | 13,762,511 | |
| -1 | -13,762,511 |
Let's try dividing by 4:
13,762,511 ÷ 4 = 3,440,627.75
If the quotient is a whole number, then 4 and 3,440,627.75 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 | 13,762,511 | |
| -1 | 13,762,511 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 79 | 287 | 553 | 607 | 3,239 | 4,249 | 22,673 | 24,887 | 47,953 | 174,209 | 335,671 | 1,966,073 | 13,762,511 |
| -1 | -7 | -41 | -79 | -287 | -553 | -607 | -3,239 | -4,249 | -22,673 | -24,887 | -47,953 | -174,209 | -335,671 | -1,966,073 | -13,762,511 |
