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 213,395, 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 | 213,395 | |
| -1 | -213,395 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 213,395.
Example:
1 x 213,395 = 213,395
and
-1 x -213,395 = 213,395
Notice both answers equal 213,395
With that explanation out of the way, let's continue. Next, we take the number 213,395 and divide it by 2:
213,395 ÷ 2 = 106,697.5
If the quotient is a whole number, then 2 and 106,697.5 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 | 213,395 | |
| -1 | -213,395 |
Now, we try dividing 213,395 by 3:
213,395 ÷ 3 = 71,131.6667
If the quotient is a whole number, then 3 and 71,131.6667 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 | 213,395 | |
| -1 | -213,395 |
Let's try dividing by 4:
213,395 ÷ 4 = 53,348.75
If the quotient is a whole number, then 4 and 53,348.75 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 | 213,395 | |
| -1 | 213,395 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 49 | 65 | 67 | 91 | 245 | 335 | 455 | 469 | 637 | 871 | 2,345 | 3,185 | 3,283 | 4,355 | 6,097 | 16,415 | 30,485 | 42,679 | 213,395 |
| -1 | -5 | -7 | -13 | -35 | -49 | -65 | -67 | -91 | -245 | -335 | -455 | -469 | -637 | -871 | -2,345 | -3,185 | -3,283 | -4,355 | -6,097 | -16,415 | -30,485 | -42,679 | -213,395 |
