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 401,555, 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 | 401,555 | |
| -1 | -401,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 401,555.
Example:
1 x 401,555 = 401,555
and
-1 x -401,555 = 401,555
Notice both answers equal 401,555
With that explanation out of the way, let's continue. Next, we take the number 401,555 and divide it by 2:
401,555 ÷ 2 = 200,777.5
If the quotient is a whole number, then 2 and 200,777.5 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 | 401,555 | |
| -1 | -401,555 |
Now, we try dividing 401,555 by 3:
401,555 ÷ 3 = 133,851.6667
If the quotient is a whole number, then 3 and 133,851.6667 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 | 401,555 | |
| -1 | -401,555 |
Let's try dividing by 4:
401,555 ÷ 4 = 100,388.75
If the quotient is a whole number, then 4 and 100,388.75 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 | 401,555 | |
| -1 | 401,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 49 | 55 | 77 | 149 | 245 | 385 | 539 | 745 | 1,043 | 1,639 | 2,695 | 5,215 | 7,301 | 8,195 | 11,473 | 36,505 | 57,365 | 80,311 | 401,555 |
| -1 | -5 | -7 | -11 | -35 | -49 | -55 | -77 | -149 | -245 | -385 | -539 | -745 | -1,043 | -1,639 | -2,695 | -5,215 | -7,301 | -8,195 | -11,473 | -36,505 | -57,365 | -80,311 | -401,555 |
