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 16,361,137, 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 | 16,361,137 | |
| -1 | -16,361,137 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,361,137.
Example:
1 x 16,361,137 = 16,361,137
and
-1 x -16,361,137 = 16,361,137
Notice both answers equal 16,361,137
With that explanation out of the way, let's continue. Next, we take the number 16,361,137 and divide it by 2:
16,361,137 ÷ 2 = 8,180,568.5
If the quotient is a whole number, then 2 and 8,180,568.5 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 | 16,361,137 | |
| -1 | -16,361,137 |
Now, we try dividing 16,361,137 by 3:
16,361,137 ÷ 3 = 5,453,712.3333
If the quotient is a whole number, then 3 and 5,453,712.3333 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 | 16,361,137 | |
| -1 | -16,361,137 |
Let's try dividing by 4:
16,361,137 ÷ 4 = 4,090,284.25
If the quotient is a whole number, then 4 and 4,090,284.25 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 | 16,361,137 | |
| -1 | 16,361,137 |
If you did it right, you will end up with this table:
| 1 | 13 | 79 | 89 | 179 | 1,027 | 1,157 | 2,327 | 7,031 | 14,141 | 15,931 | 91,403 | 183,833 | 207,103 | 1,258,549 | 16,361,137 |
| -1 | -13 | -79 | -89 | -179 | -1,027 | -1,157 | -2,327 | -7,031 | -14,141 | -15,931 | -91,403 | -183,833 | -207,103 | -1,258,549 | -16,361,137 |
