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 13,374,803, 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 | 13,374,803 | |
| -1 | -13,374,803 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,374,803.
Example:
1 x 13,374,803 = 13,374,803
and
-1 x -13,374,803 = 13,374,803
Notice both answers equal 13,374,803
With that explanation out of the way, let's continue. Next, we take the number 13,374,803 and divide it by 2:
13,374,803 ÷ 2 = 6,687,401.5
If the quotient is a whole number, then 2 and 6,687,401.5 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 | 13,374,803 | |
| -1 | -13,374,803 |
Now, we try dividing 13,374,803 by 3:
13,374,803 ÷ 3 = 4,458,267.6667
If the quotient is a whole number, then 3 and 4,458,267.6667 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 | 13,374,803 | |
| -1 | -13,374,803 |
Let's try dividing by 4:
13,374,803 ÷ 4 = 3,343,700.75
If the quotient is a whole number, then 4 and 3,343,700.75 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 | 13,374,803 | |
| -1 | 13,374,803 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 173 | 247 | 313 | 2,249 | 3,287 | 4,069 | 5,947 | 42,731 | 54,149 | 77,311 | 703,937 | 1,028,831 | 13,374,803 |
| -1 | -13 | -19 | -173 | -247 | -313 | -2,249 | -3,287 | -4,069 | -5,947 | -42,731 | -54,149 | -77,311 | -703,937 | -1,028,831 | -13,374,803 |
