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 212,214,353, 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 | 212,214,353 | |
| -1 | -212,214,353 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 212,214,353.
Example:
1 x 212,214,353 = 212,214,353
and
-1 x -212,214,353 = 212,214,353
Notice both answers equal 212,214,353
With that explanation out of the way, let's continue. Next, we take the number 212,214,353 and divide it by 2:
212,214,353 ÷ 2 = 106,107,176.5
If the quotient is a whole number, then 2 and 106,107,176.5 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 | 212,214,353 | |
| -1 | -212,214,353 |
Now, we try dividing 212,214,353 by 3:
212,214,353 ÷ 3 = 70,738,117.6667
If the quotient is a whole number, then 3 and 70,738,117.6667 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 | 212,214,353 | |
| -1 | -212,214,353 |
Let's try dividing by 4:
212,214,353 ÷ 4 = 53,053,588.25
If the quotient is a whole number, then 4 and 53,053,588.25 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 | 212,214,353 | |
| -1 | 212,214,353 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 47 | 299 | 611 | 1,081 | 14,053 | 15,101 | 196,313 | 347,323 | 709,747 | 4,515,199 | 9,226,711 | 16,324,181 | 212,214,353 |
| -1 | -13 | -23 | -47 | -299 | -611 | -1,081 | -14,053 | -15,101 | -196,313 | -347,323 | -709,747 | -4,515,199 | -9,226,711 | -16,324,181 | -212,214,353 |
