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 16,941,097, 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 | 16,941,097 | |
| -1 | -16,941,097 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,941,097.
Example:
1 x 16,941,097 = 16,941,097
and
-1 x -16,941,097 = 16,941,097
Notice both answers equal 16,941,097
With that explanation out of the way, let's continue. Next, we take the number 16,941,097 and divide it by 2:
16,941,097 ÷ 2 = 8,470,548.5
If the quotient is a whole number, then 2 and 8,470,548.5 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 | 16,941,097 | |
| -1 | -16,941,097 |
Now, we try dividing 16,941,097 by 3:
16,941,097 ÷ 3 = 5,647,032.3333
If the quotient is a whole number, then 3 and 5,647,032.3333 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 | 16,941,097 | |
| -1 | -16,941,097 |
Let's try dividing by 4:
16,941,097 ÷ 4 = 4,235,274.25
If the quotient is a whole number, then 4 and 4,235,274.25 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 | 16,941,097 | |
| -1 | 16,941,097 |
If you did it right, you will end up with this table:
| 1 | 31 | 43 | 71 | 179 | 1,333 | 2,201 | 3,053 | 5,549 | 7,697 | 12,709 | 94,643 | 238,607 | 393,979 | 546,487 | 16,941,097 |
| -1 | -31 | -43 | -71 | -179 | -1,333 | -2,201 | -3,053 | -5,549 | -7,697 | -12,709 | -94,643 | -238,607 | -393,979 | -546,487 | -16,941,097 |
