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 254,210,333, 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 | 254,210,333 | |
| -1 | -254,210,333 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 254,210,333.
Example:
1 x 254,210,333 = 254,210,333
and
-1 x -254,210,333 = 254,210,333
Notice both answers equal 254,210,333
With that explanation out of the way, let's continue. Next, we take the number 254,210,333 and divide it by 2:
254,210,333 ÷ 2 = 127,105,166.5
If the quotient is a whole number, then 2 and 127,105,166.5 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 | 254,210,333 | |
| -1 | -254,210,333 |
Now, we try dividing 254,210,333 by 3:
254,210,333 ÷ 3 = 84,736,777.6667
If the quotient is a whole number, then 3 and 84,736,777.6667 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 | 254,210,333 | |
| -1 | -254,210,333 |
Let's try dividing by 4:
254,210,333 ÷ 4 = 63,552,583.25
If the quotient is a whole number, then 4 and 63,552,583.25 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 | 254,210,333 | |
| -1 | 254,210,333 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 389 | 2,957 | 5,057 | 6,613 | 38,441 | 50,269 | 85,969 | 653,497 | 1,150,273 | 14,953,549 | 19,554,641 | 254,210,333 |
| -1 | -13 | -17 | -221 | -389 | -2,957 | -5,057 | -6,613 | -38,441 | -50,269 | -85,969 | -653,497 | -1,150,273 | -14,953,549 | -19,554,641 | -254,210,333 |
