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 333,621,415, 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 | 333,621,415 | |
| -1 | -333,621,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 333,621,415.
Example:
1 x 333,621,415 = 333,621,415
and
-1 x -333,621,415 = 333,621,415
Notice both answers equal 333,621,415
With that explanation out of the way, let's continue. Next, we take the number 333,621,415 and divide it by 2:
333,621,415 ÷ 2 = 166,810,707.5
If the quotient is a whole number, then 2 and 166,810,707.5 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 | 333,621,415 | |
| -1 | -333,621,415 |
Now, we try dividing 333,621,415 by 3:
333,621,415 ÷ 3 = 111,207,138.3333
If the quotient is a whole number, then 3 and 111,207,138.3333 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 | 333,621,415 | |
| -1 | -333,621,415 |
Let's try dividing by 4:
333,621,415 ÷ 4 = 83,405,353.75
If the quotient is a whole number, then 4 and 83,405,353.75 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 | 333,621,415 | |
| -1 | 333,621,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 185 | 347 | 1,735 | 5,197 | 12,839 | 25,985 | 64,195 | 192,289 | 961,445 | 1,803,359 | 9,016,795 | 66,724,283 | 333,621,415 |
| -1 | -5 | -37 | -185 | -347 | -1,735 | -5,197 | -12,839 | -25,985 | -64,195 | -192,289 | -961,445 | -1,803,359 | -9,016,795 | -66,724,283 | -333,621,415 |
