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 54,331,145, 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 | 54,331,145 | |
| -1 | -54,331,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,331,145.
Example:
1 x 54,331,145 = 54,331,145
and
-1 x -54,331,145 = 54,331,145
Notice both answers equal 54,331,145
With that explanation out of the way, let's continue. Next, we take the number 54,331,145 and divide it by 2:
54,331,145 ÷ 2 = 27,165,572.5
If the quotient is a whole number, then 2 and 27,165,572.5 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 | 54,331,145 | |
| -1 | -54,331,145 |
Now, we try dividing 54,331,145 by 3:
54,331,145 ÷ 3 = 18,110,381.6667
If the quotient is a whole number, then 3 and 18,110,381.6667 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 | 54,331,145 | |
| -1 | -54,331,145 |
Let's try dividing by 4:
54,331,145 ÷ 4 = 13,582,786.25
If the quotient is a whole number, then 4 and 13,582,786.25 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 | 54,331,145 | |
| -1 | 54,331,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 43 | 55 | 215 | 473 | 2,365 | 22,973 | 114,865 | 252,703 | 987,839 | 1,263,515 | 4,939,195 | 10,866,229 | 54,331,145 |
| -1 | -5 | -11 | -43 | -55 | -215 | -473 | -2,365 | -22,973 | -114,865 | -252,703 | -987,839 | -1,263,515 | -4,939,195 | -10,866,229 | -54,331,145 |
