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 54,451,309, 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 | 54,451,309 | |
| -1 | -54,451,309 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,451,309.
Example:
1 x 54,451,309 = 54,451,309
and
-1 x -54,451,309 = 54,451,309
Notice both answers equal 54,451,309
With that explanation out of the way, let's continue. Next, we take the number 54,451,309 and divide it by 2:
54,451,309 ÷ 2 = 27,225,654.5
If the quotient is a whole number, then 2 and 27,225,654.5 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 | 54,451,309 | |
| -1 | -54,451,309 |
Now, we try dividing 54,451,309 by 3:
54,451,309 ÷ 3 = 18,150,436.3333
If the quotient is a whole number, then 3 and 18,150,436.3333 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 | 54,451,309 | |
| -1 | -54,451,309 |
Let's try dividing by 4:
54,451,309 ÷ 4 = 13,612,827.25
If the quotient is a whole number, then 4 and 13,612,827.25 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 | 54,451,309 | |
| -1 | 54,451,309 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 353 | 379 | 407 | 3,883 | 4,169 | 13,061 | 14,023 | 133,787 | 143,671 | 154,253 | 1,471,657 | 4,950,119 | 54,451,309 |
| -1 | -11 | -37 | -353 | -379 | -407 | -3,883 | -4,169 | -13,061 | -14,023 | -133,787 | -143,671 | -154,253 | -1,471,657 | -4,950,119 | -54,451,309 |
