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 333,153,457, 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 | 333,153,457 | |
| -1 | -333,153,457 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 333,153,457.
Example:
1 x 333,153,457 = 333,153,457
and
-1 x -333,153,457 = 333,153,457
Notice both answers equal 333,153,457
With that explanation out of the way, let's continue. Next, we take the number 333,153,457 and divide it by 2:
333,153,457 ÷ 2 = 166,576,728.5
If the quotient is a whole number, then 2 and 166,576,728.5 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 | 333,153,457 | |
| -1 | -333,153,457 |
Now, we try dividing 333,153,457 by 3:
333,153,457 ÷ 3 = 111,051,152.3333
If the quotient is a whole number, then 3 and 111,051,152.3333 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 | 333,153,457 | |
| -1 | -333,153,457 |
Let's try dividing by 4:
333,153,457 ÷ 4 = 83,288,364.25
If the quotient is a whole number, then 4 and 83,288,364.25 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 | 333,153,457 | |
| -1 | 333,153,457 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 457 | 3,199 | 5,941 | 8,011 | 41,587 | 56,077 | 104,143 | 729,001 | 3,661,027 | 25,627,189 | 47,593,351 | 333,153,457 |
| -1 | -7 | -13 | -91 | -457 | -3,199 | -5,941 | -8,011 | -41,587 | -56,077 | -104,143 | -729,001 | -3,661,027 | -25,627,189 | -47,593,351 | -333,153,457 |
