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 54,331,445, 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 | 54,331,445 | |
| -1 | -54,331,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,331,445.
Example:
1 x 54,331,445 = 54,331,445
and
-1 x -54,331,445 = 54,331,445
Notice both answers equal 54,331,445
With that explanation out of the way, let's continue. Next, we take the number 54,331,445 and divide it by 2:
54,331,445 ÷ 2 = 27,165,722.5
If the quotient is a whole number, then 2 and 27,165,722.5 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 | 54,331,445 | |
| -1 | -54,331,445 |
Now, we try dividing 54,331,445 by 3:
54,331,445 ÷ 3 = 18,110,481.6667
If the quotient is a whole number, then 3 and 18,110,481.6667 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 | 54,331,445 | |
| -1 | -54,331,445 |
Let's try dividing by 4:
54,331,445 ÷ 4 = 13,582,861.25
If the quotient is a whole number, then 4 and 13,582,861.25 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 | 54,331,445 | |
| -1 | 54,331,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 211 | 245 | 1,051 | 1,055 | 1,477 | 5,255 | 7,357 | 7,385 | 10,339 | 36,785 | 51,499 | 51,695 | 221,761 | 257,495 | 1,108,805 | 1,552,327 | 7,761,635 | 10,866,289 | 54,331,445 |
| -1 | -5 | -7 | -35 | -49 | -211 | -245 | -1,051 | -1,055 | -1,477 | -5,255 | -7,357 | -7,385 | -10,339 | -36,785 | -51,499 | -51,695 | -221,761 | -257,495 | -1,108,805 | -1,552,327 | -7,761,635 | -10,866,289 | -54,331,445 |
