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 54,577,405, 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 | 54,577,405 | |
| -1 | -54,577,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 54,577,405.
Example:
1 x 54,577,405 = 54,577,405
and
-1 x -54,577,405 = 54,577,405
Notice both answers equal 54,577,405
With that explanation out of the way, let's continue. Next, we take the number 54,577,405 and divide it by 2:
54,577,405 ÷ 2 = 27,288,702.5
If the quotient is a whole number, then 2 and 27,288,702.5 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 | 54,577,405 | |
| -1 | -54,577,405 |
Now, we try dividing 54,577,405 by 3:
54,577,405 ÷ 3 = 18,192,468.3333
If the quotient is a whole number, then 3 and 18,192,468.3333 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 | 54,577,405 | |
| -1 | -54,577,405 |
Let's try dividing by 4:
54,577,405 ÷ 4 = 13,644,351.25
If the quotient is a whole number, then 4 and 13,644,351.25 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 | 54,577,405 | |
| -1 | 54,577,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 37 | 95 | 185 | 703 | 3,515 | 15,527 | 77,635 | 295,013 | 574,499 | 1,475,065 | 2,872,495 | 10,915,481 | 54,577,405 |
| -1 | -5 | -19 | -37 | -95 | -185 | -703 | -3,515 | -15,527 | -77,635 | -295,013 | -574,499 | -1,475,065 | -2,872,495 | -10,915,481 | -54,577,405 |
