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 16,342,975, 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 | 16,342,975 | |
| -1 | -16,342,975 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,342,975.
Example:
1 x 16,342,975 = 16,342,975
and
-1 x -16,342,975 = 16,342,975
Notice both answers equal 16,342,975
With that explanation out of the way, let's continue. Next, we take the number 16,342,975 and divide it by 2:
16,342,975 ÷ 2 = 8,171,487.5
If the quotient is a whole number, then 2 and 8,171,487.5 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 | 16,342,975 | |
| -1 | -16,342,975 |
Now, we try dividing 16,342,975 by 3:
16,342,975 ÷ 3 = 5,447,658.3333
If the quotient is a whole number, then 3 and 5,447,658.3333 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 | 16,342,975 | |
| -1 | -16,342,975 |
Let's try dividing by 4:
16,342,975 ÷ 4 = 4,085,743.75
If the quotient is a whole number, then 4 and 4,085,743.75 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 | 16,342,975 | |
| -1 | 16,342,975 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 67 | 275 | 335 | 737 | 887 | 1,675 | 3,685 | 4,435 | 9,757 | 18,425 | 22,175 | 48,785 | 59,429 | 243,925 | 297,145 | 653,719 | 1,485,725 | 3,268,595 | 16,342,975 |
| -1 | -5 | -11 | -25 | -55 | -67 | -275 | -335 | -737 | -887 | -1,675 | -3,685 | -4,435 | -9,757 | -18,425 | -22,175 | -48,785 | -59,429 | -243,925 | -297,145 | -653,719 | -1,485,725 | -3,268,595 | -16,342,975 |
