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 53,240,135, 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 | 53,240,135 | |
| -1 | -53,240,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,240,135.
Example:
1 x 53,240,135 = 53,240,135
and
-1 x -53,240,135 = 53,240,135
Notice both answers equal 53,240,135
With that explanation out of the way, let's continue. Next, we take the number 53,240,135 and divide it by 2:
53,240,135 ÷ 2 = 26,620,067.5
If the quotient is a whole number, then 2 and 26,620,067.5 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 | 53,240,135 | |
| -1 | -53,240,135 |
Now, we try dividing 53,240,135 by 3:
53,240,135 ÷ 3 = 17,746,711.6667
If the quotient is a whole number, then 3 and 17,746,711.6667 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 | 53,240,135 | |
| -1 | -53,240,135 |
Let's try dividing by 4:
53,240,135 ÷ 4 = 13,310,033.75
If the quotient is a whole number, then 4 and 13,310,033.75 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 | 53,240,135 | |
| -1 | 53,240,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 223 | 1,115 | 2,899 | 3,673 | 14,495 | 18,365 | 47,749 | 238,745 | 819,079 | 4,095,395 | 10,648,027 | 53,240,135 |
| -1 | -5 | -13 | -65 | -223 | -1,115 | -2,899 | -3,673 | -14,495 | -18,365 | -47,749 | -238,745 | -819,079 | -4,095,395 | -10,648,027 | -53,240,135 |
