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 12,351,367, 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 | 12,351,367 | |
| -1 | -12,351,367 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,351,367.
Example:
1 x 12,351,367 = 12,351,367
and
-1 x -12,351,367 = 12,351,367
Notice both answers equal 12,351,367
With that explanation out of the way, let's continue. Next, we take the number 12,351,367 and divide it by 2:
12,351,367 ÷ 2 = 6,175,683.5
If the quotient is a whole number, then 2 and 6,175,683.5 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 | 12,351,367 | |
| -1 | -12,351,367 |
Now, we try dividing 12,351,367 by 3:
12,351,367 ÷ 3 = 4,117,122.3333
If the quotient is a whole number, then 3 and 4,117,122.3333 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 | 12,351,367 | |
| -1 | -12,351,367 |
Let's try dividing by 4:
12,351,367 ÷ 4 = 3,087,841.75
If the quotient is a whole number, then 4 and 3,087,841.75 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 | 12,351,367 | |
| -1 | 12,351,367 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 271 | 383 | 1,897 | 2,681 | 4,607 | 6,511 | 32,249 | 45,577 | 103,793 | 726,551 | 1,764,481 | 12,351,367 |
| -1 | -7 | -17 | -119 | -271 | -383 | -1,897 | -2,681 | -4,607 | -6,511 | -32,249 | -45,577 | -103,793 | -726,551 | -1,764,481 | -12,351,367 |
