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 16,088,597, 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 | 16,088,597 | |
| -1 | -16,088,597 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,088,597.
Example:
1 x 16,088,597 = 16,088,597
and
-1 x -16,088,597 = 16,088,597
Notice both answers equal 16,088,597
With that explanation out of the way, let's continue. Next, we take the number 16,088,597 and divide it by 2:
16,088,597 ÷ 2 = 8,044,298.5
If the quotient is a whole number, then 2 and 8,044,298.5 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 | 16,088,597 | |
| -1 | -16,088,597 |
Now, we try dividing 16,088,597 by 3:
16,088,597 ÷ 3 = 5,362,865.6667
If the quotient is a whole number, then 3 and 5,362,865.6667 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 | 16,088,597 | |
| -1 | -16,088,597 |
Let's try dividing by 4:
16,088,597 ÷ 4 = 4,022,149.25
If the quotient is a whole number, then 4 and 4,022,149.25 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 | 16,088,597 | |
| -1 | 16,088,597 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 151 | 217 | 491 | 1,057 | 3,437 | 4,681 | 15,221 | 32,767 | 74,141 | 106,547 | 518,987 | 2,298,371 | 16,088,597 |
| -1 | -7 | -31 | -151 | -217 | -491 | -1,057 | -3,437 | -4,681 | -15,221 | -32,767 | -74,141 | -106,547 | -518,987 | -2,298,371 | -16,088,597 |
