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 16,435,141, 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 | 16,435,141 | |
| -1 | -16,435,141 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,435,141.
Example:
1 x 16,435,141 = 16,435,141
and
-1 x -16,435,141 = 16,435,141
Notice both answers equal 16,435,141
With that explanation out of the way, let's continue. Next, we take the number 16,435,141 and divide it by 2:
16,435,141 ÷ 2 = 8,217,570.5
If the quotient is a whole number, then 2 and 8,217,570.5 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 | 16,435,141 | |
| -1 | -16,435,141 |
Now, we try dividing 16,435,141 by 3:
16,435,141 ÷ 3 = 5,478,380.3333
If the quotient is a whole number, then 3 and 5,478,380.3333 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 | 16,435,141 | |
| -1 | -16,435,141 |
Let's try dividing by 4:
16,435,141 ÷ 4 = 4,108,785.25
If the quotient is a whole number, then 4 and 4,108,785.25 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 | 16,435,141 | |
| -1 | 16,435,141 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 37 | 53 | 289 | 493 | 629 | 901 | 1,073 | 1,537 | 1,961 | 8,381 | 10,693 | 15,317 | 18,241 | 26,129 | 33,337 | 56,869 | 310,097 | 444,193 | 566,729 | 966,773 | 16,435,141 |
| -1 | -17 | -29 | -37 | -53 | -289 | -493 | -629 | -901 | -1,073 | -1,537 | -1,961 | -8,381 | -10,693 | -15,317 | -18,241 | -26,129 | -33,337 | -56,869 | -310,097 | -444,193 | -566,729 | -966,773 | -16,435,141 |
