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 16,106,701, 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 | 16,106,701 | |
| -1 | -16,106,701 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,106,701.
Example:
1 x 16,106,701 = 16,106,701
and
-1 x -16,106,701 = 16,106,701
Notice both answers equal 16,106,701
With that explanation out of the way, let's continue. Next, we take the number 16,106,701 and divide it by 2:
16,106,701 ÷ 2 = 8,053,350.5
If the quotient is a whole number, then 2 and 8,053,350.5 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 | 16,106,701 | |
| -1 | -16,106,701 |
Now, we try dividing 16,106,701 by 3:
16,106,701 ÷ 3 = 5,368,900.3333
If the quotient is a whole number, then 3 and 5,368,900.3333 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 | 16,106,701 | |
| -1 | -16,106,701 |
Let's try dividing by 4:
16,106,701 ÷ 4 = 4,026,675.25
If the quotient is a whole number, then 4 and 4,026,675.25 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 | 16,106,701 | |
| -1 | 16,106,701 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 31 | 221 | 403 | 527 | 2,351 | 6,851 | 30,563 | 39,967 | 72,881 | 519,571 | 947,453 | 1,238,977 | 16,106,701 |
| -1 | -13 | -17 | -31 | -221 | -403 | -527 | -2,351 | -6,851 | -30,563 | -39,967 | -72,881 | -519,571 | -947,453 | -1,238,977 | -16,106,701 |
