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 16,973,671, 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 | 16,973,671 | |
| -1 | -16,973,671 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,973,671.
Example:
1 x 16,973,671 = 16,973,671
and
-1 x -16,973,671 = 16,973,671
Notice both answers equal 16,973,671
With that explanation out of the way, let's continue. Next, we take the number 16,973,671 and divide it by 2:
16,973,671 ÷ 2 = 8,486,835.5
If the quotient is a whole number, then 2 and 8,486,835.5 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 | 16,973,671 | |
| -1 | -16,973,671 |
Now, we try dividing 16,973,671 by 3:
16,973,671 ÷ 3 = 5,657,890.3333
If the quotient is a whole number, then 3 and 5,657,890.3333 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 | 16,973,671 | |
| -1 | -16,973,671 |
Let's try dividing by 4:
16,973,671 ÷ 4 = 4,243,417.75
If the quotient is a whole number, then 4 and 4,243,417.75 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 | 16,973,671 | |
| -1 | 16,973,671 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 29 | 143 | 319 | 377 | 4,093 | 4,147 | 45,023 | 53,209 | 118,697 | 585,299 | 1,305,667 | 1,543,061 | 16,973,671 |
| -1 | -11 | -13 | -29 | -143 | -319 | -377 | -4,093 | -4,147 | -45,023 | -53,209 | -118,697 | -585,299 | -1,305,667 | -1,543,061 | -16,973,671 |
