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 16,154,957, 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 | 16,154,957 | |
| -1 | -16,154,957 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,154,957.
Example:
1 x 16,154,957 = 16,154,957
and
-1 x -16,154,957 = 16,154,957
Notice both answers equal 16,154,957
With that explanation out of the way, let's continue. Next, we take the number 16,154,957 and divide it by 2:
16,154,957 ÷ 2 = 8,077,478.5
If the quotient is a whole number, then 2 and 8,077,478.5 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 | 16,154,957 | |
| -1 | -16,154,957 |
Now, we try dividing 16,154,957 by 3:
16,154,957 ÷ 3 = 5,384,985.6667
If the quotient is a whole number, then 3 and 5,384,985.6667 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 | 16,154,957 | |
| -1 | -16,154,957 |
Let's try dividing by 4:
16,154,957 ÷ 4 = 4,038,739.25
If the quotient is a whole number, then 4 and 4,038,739.25 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 | 16,154,957 | |
| -1 | 16,154,957 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 343 | 637 | 3,623 | 4,459 | 25,361 | 47,099 | 177,527 | 329,693 | 1,242,689 | 2,307,851 | 16,154,957 |
| -1 | -7 | -13 | -49 | -91 | -343 | -637 | -3,623 | -4,459 | -25,361 | -47,099 | -177,527 | -329,693 | -1,242,689 | -2,307,851 | -16,154,957 |
