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 16,141,573, 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 | 16,141,573 | |
| -1 | -16,141,573 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,141,573.
Example:
1 x 16,141,573 = 16,141,573
and
-1 x -16,141,573 = 16,141,573
Notice both answers equal 16,141,573
With that explanation out of the way, let's continue. Next, we take the number 16,141,573 and divide it by 2:
16,141,573 ÷ 2 = 8,070,786.5
If the quotient is a whole number, then 2 and 8,070,786.5 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 | 16,141,573 | |
| -1 | -16,141,573 |
Now, we try dividing 16,141,573 by 3:
16,141,573 ÷ 3 = 5,380,524.3333
If the quotient is a whole number, then 3 and 5,380,524.3333 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 | 16,141,573 | |
| -1 | -16,141,573 |
Let's try dividing by 4:
16,141,573 ÷ 4 = 4,035,393.25
If the quotient is a whole number, then 4 and 4,035,393.25 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 | 16,141,573 | |
| -1 | 16,141,573 |
If you did it right, you will end up with this table:
| 1 | 7 | 67 | 127 | 271 | 469 | 889 | 1,897 | 8,509 | 18,157 | 34,417 | 59,563 | 127,099 | 240,919 | 2,305,939 | 16,141,573 |
| -1 | -7 | -67 | -127 | -271 | -469 | -889 | -1,897 | -8,509 | -18,157 | -34,417 | -59,563 | -127,099 | -240,919 | -2,305,939 | -16,141,573 |
