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 53,315,405, 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 | 53,315,405 | |
| -1 | -53,315,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,315,405.
Example:
1 x 53,315,405 = 53,315,405
and
-1 x -53,315,405 = 53,315,405
Notice both answers equal 53,315,405
With that explanation out of the way, let's continue. Next, we take the number 53,315,405 and divide it by 2:
53,315,405 ÷ 2 = 26,657,702.5
If the quotient is a whole number, then 2 and 26,657,702.5 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 | 53,315,405 | |
| -1 | -53,315,405 |
Now, we try dividing 53,315,405 by 3:
53,315,405 ÷ 3 = 17,771,801.6667
If the quotient is a whole number, then 3 and 17,771,801.6667 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 | 53,315,405 | |
| -1 | -53,315,405 |
Let's try dividing by 4:
53,315,405 ÷ 4 = 13,328,851.25
If the quotient is a whole number, then 4 and 13,328,851.25 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 | 53,315,405 | |
| -1 | 53,315,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 74,567 | 372,835 | 820,237 | 969,371 | 4,101,185 | 4,846,855 | 10,663,081 | 53,315,405 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -74,567 | -372,835 | -820,237 | -969,371 | -4,101,185 | -4,846,855 | -10,663,081 | -53,315,405 |
