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 401,635, 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 | 401,635 | |
| -1 | -401,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 401,635.
Example:
1 x 401,635 = 401,635
and
-1 x -401,635 = 401,635
Notice both answers equal 401,635
With that explanation out of the way, let's continue. Next, we take the number 401,635 and divide it by 2:
401,635 ÷ 2 = 200,817.5
If the quotient is a whole number, then 2 and 200,817.5 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 | 401,635 | |
| -1 | -401,635 |
Now, we try dividing 401,635 by 3:
401,635 ÷ 3 = 133,878.3333
If the quotient is a whole number, then 3 and 133,878.3333 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 | 401,635 | |
| -1 | -401,635 |
Let's try dividing by 4:
401,635 ÷ 4 = 100,408.75
If the quotient is a whole number, then 4 and 100,408.75 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 | 401,635 | |
| -1 | 401,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 37 | 65 | 167 | 185 | 481 | 835 | 2,171 | 2,405 | 6,179 | 10,855 | 30,895 | 80,327 | 401,635 |
| -1 | -5 | -13 | -37 | -65 | -167 | -185 | -481 | -835 | -2,171 | -2,405 | -6,179 | -10,855 | -30,895 | -80,327 | -401,635 |
