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 54,578,711, 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 | 54,578,711 | |
| -1 | -54,578,711 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,578,711.
Example:
1 x 54,578,711 = 54,578,711
and
-1 x -54,578,711 = 54,578,711
Notice both answers equal 54,578,711
With that explanation out of the way, let's continue. Next, we take the number 54,578,711 and divide it by 2:
54,578,711 ÷ 2 = 27,289,355.5
If the quotient is a whole number, then 2 and 27,289,355.5 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 | 54,578,711 | |
| -1 | -54,578,711 |
Now, we try dividing 54,578,711 by 3:
54,578,711 ÷ 3 = 18,192,903.6667
If the quotient is a whole number, then 3 and 18,192,903.6667 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 | 54,578,711 | |
| -1 | -54,578,711 |
Let's try dividing by 4:
54,578,711 ÷ 4 = 13,644,677.75
If the quotient is a whole number, then 4 and 13,644,677.75 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 | 54,578,711 | |
| -1 | 54,578,711 |
If you did it right, you will end up with this table:
| 1 | 11 | 53 | 179 | 523 | 583 | 1,969 | 5,753 | 9,487 | 27,719 | 93,617 | 104,357 | 304,909 | 1,029,787 | 4,961,701 | 54,578,711 |
| -1 | -11 | -53 | -179 | -523 | -583 | -1,969 | -5,753 | -9,487 | -27,719 | -93,617 | -104,357 | -304,909 | -1,029,787 | -4,961,701 | -54,578,711 |
