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 13,672,373, 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 | 13,672,373 | |
| -1 | -13,672,373 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,672,373.
Example:
1 x 13,672,373 = 13,672,373
and
-1 x -13,672,373 = 13,672,373
Notice both answers equal 13,672,373
With that explanation out of the way, let's continue. Next, we take the number 13,672,373 and divide it by 2:
13,672,373 ÷ 2 = 6,836,186.5
If the quotient is a whole number, then 2 and 6,836,186.5 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 | 13,672,373 | |
| -1 | -13,672,373 |
Now, we try dividing 13,672,373 by 3:
13,672,373 ÷ 3 = 4,557,457.6667
If the quotient is a whole number, then 3 and 4,557,457.6667 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 | 13,672,373 | |
| -1 | -13,672,373 |
Let's try dividing by 4:
13,672,373 ÷ 4 = 3,418,093.25
If the quotient is a whole number, then 4 and 3,418,093.25 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 | 13,672,373 | |
| -1 | 13,672,373 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 23 | 143 | 253 | 299 | 3,289 | 4,157 | 45,727 | 54,041 | 95,611 | 594,451 | 1,051,721 | 1,242,943 | 13,672,373 |
| -1 | -11 | -13 | -23 | -143 | -253 | -299 | -3,289 | -4,157 | -45,727 | -54,041 | -95,611 | -594,451 | -1,051,721 | -1,242,943 | -13,672,373 |
