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 16,278,877, 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 | 16,278,877 | |
| -1 | -16,278,877 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,278,877.
Example:
1 x 16,278,877 = 16,278,877
and
-1 x -16,278,877 = 16,278,877
Notice both answers equal 16,278,877
With that explanation out of the way, let's continue. Next, we take the number 16,278,877 and divide it by 2:
16,278,877 ÷ 2 = 8,139,438.5
If the quotient is a whole number, then 2 and 8,139,438.5 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 | 16,278,877 | |
| -1 | -16,278,877 |
Now, we try dividing 16,278,877 by 3:
16,278,877 ÷ 3 = 5,426,292.3333
If the quotient is a whole number, then 3 and 5,426,292.3333 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 | 16,278,877 | |
| -1 | -16,278,877 |
Let's try dividing by 4:
16,278,877 ÷ 4 = 4,069,719.25
If the quotient is a whole number, then 4 and 4,069,719.25 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 | 16,278,877 | |
| -1 | 16,278,877 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 101 | 323 | 499 | 1,717 | 1,919 | 8,483 | 9,481 | 32,623 | 50,399 | 161,177 | 856,783 | 957,581 | 16,278,877 |
| -1 | -17 | -19 | -101 | -323 | -499 | -1,717 | -1,919 | -8,483 | -9,481 | -32,623 | -50,399 | -161,177 | -856,783 | -957,581 | -16,278,877 |
