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 16,142,035, 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 | 16,142,035 | |
| -1 | -16,142,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,142,035.
Example:
1 x 16,142,035 = 16,142,035
and
-1 x -16,142,035 = 16,142,035
Notice both answers equal 16,142,035
With that explanation out of the way, let's continue. Next, we take the number 16,142,035 and divide it by 2:
16,142,035 ÷ 2 = 8,071,017.5
If the quotient is a whole number, then 2 and 8,071,017.5 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 | 16,142,035 | |
| -1 | -16,142,035 |
Now, we try dividing 16,142,035 by 3:
16,142,035 ÷ 3 = 5,380,678.3333
If the quotient is a whole number, then 3 and 5,380,678.3333 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 | 16,142,035 | |
| -1 | -16,142,035 |
Let's try dividing by 4:
16,142,035 ÷ 4 = 4,035,508.75
If the quotient is a whole number, then 4 and 4,035,508.75 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 | 16,142,035 | |
| -1 | 16,142,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 169 | 455 | 845 | 1,183 | 2,729 | 5,915 | 13,645 | 19,103 | 35,477 | 95,515 | 177,385 | 248,339 | 461,201 | 1,241,695 | 2,306,005 | 3,228,407 | 16,142,035 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -169 | -455 | -845 | -1,183 | -2,729 | -5,915 | -13,645 | -19,103 | -35,477 | -95,515 | -177,385 | -248,339 | -461,201 | -1,241,695 | -2,306,005 | -3,228,407 | -16,142,035 |
