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 56,464,331, 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 | 56,464,331 | |
| -1 | -56,464,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,464,331.
Example:
1 x 56,464,331 = 56,464,331
and
-1 x -56,464,331 = 56,464,331
Notice both answers equal 56,464,331
With that explanation out of the way, let's continue. Next, we take the number 56,464,331 and divide it by 2:
56,464,331 ÷ 2 = 28,232,165.5
If the quotient is a whole number, then 2 and 28,232,165.5 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 | 56,464,331 | |
| -1 | -56,464,331 |
Now, we try dividing 56,464,331 by 3:
56,464,331 ÷ 3 = 18,821,443.6667
If the quotient is a whole number, then 3 and 18,821,443.6667 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 | 56,464,331 | |
| -1 | -56,464,331 |
Let's try dividing by 4:
56,464,331 ÷ 4 = 14,116,082.75
If the quotient is a whole number, then 4 and 14,116,082.75 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 | 56,464,331 | |
| -1 | 56,464,331 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 37 | 77 | 259 | 407 | 2,849 | 19,819 | 138,733 | 218,009 | 733,303 | 1,526,063 | 5,133,121 | 8,066,333 | 56,464,331 |
| -1 | -7 | -11 | -37 | -77 | -259 | -407 | -2,849 | -19,819 | -138,733 | -218,009 | -733,303 | -1,526,063 | -5,133,121 | -8,066,333 | -56,464,331 |
