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 216,434,999, 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 | 216,434,999 | |
| -1 | -216,434,999 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 216,434,999.
Example:
1 x 216,434,999 = 216,434,999
and
-1 x -216,434,999 = 216,434,999
Notice both answers equal 216,434,999
With that explanation out of the way, let's continue. Next, we take the number 216,434,999 and divide it by 2:
216,434,999 ÷ 2 = 108,217,499.5
If the quotient is a whole number, then 2 and 108,217,499.5 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 | 216,434,999 | |
| -1 | -216,434,999 |
Now, we try dividing 216,434,999 by 3:
216,434,999 ÷ 3 = 72,144,999.6667
If the quotient is a whole number, then 3 and 72,144,999.6667 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 | 216,434,999 | |
| -1 | -216,434,999 |
Let's try dividing by 4:
216,434,999 ÷ 4 = 54,108,749.75
If the quotient is a whole number, then 4 and 54,108,749.75 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 | 216,434,999 | |
| -1 | 216,434,999 |
If you did it right, you will end up with this table:
| 1 | 11 | 73 | 107 | 121 | 229 | 803 | 1,177 | 2,519 | 7,811 | 8,833 | 12,947 | 16,717 | 24,503 | 27,709 | 85,921 | 183,887 | 269,533 | 945,131 | 1,788,719 | 2,022,757 | 2,964,863 | 19,675,909 | 216,434,999 |
| -1 | -11 | -73 | -107 | -121 | -229 | -803 | -1,177 | -2,519 | -7,811 | -8,833 | -12,947 | -16,717 | -24,503 | -27,709 | -85,921 | -183,887 | -269,533 | -945,131 | -1,788,719 | -2,022,757 | -2,964,863 | -19,675,909 | -216,434,999 |
