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 53,512,105, 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 | 53,512,105 | |
| -1 | -53,512,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,512,105.
Example:
1 x 53,512,105 = 53,512,105
and
-1 x -53,512,105 = 53,512,105
Notice both answers equal 53,512,105
With that explanation out of the way, let's continue. Next, we take the number 53,512,105 and divide it by 2:
53,512,105 ÷ 2 = 26,756,052.5
If the quotient is a whole number, then 2 and 26,756,052.5 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 | 53,512,105 | |
| -1 | -53,512,105 |
Now, we try dividing 53,512,105 by 3:
53,512,105 ÷ 3 = 17,837,368.3333
If the quotient is a whole number, then 3 and 17,837,368.3333 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 | 53,512,105 | |
| -1 | -53,512,105 |
Let's try dividing by 4:
53,512,105 ÷ 4 = 13,378,026.25
If the quotient is a whole number, then 4 and 13,378,026.25 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 | 53,512,105 | |
| -1 | 53,512,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 103 | 145 | 515 | 2,987 | 3,583 | 14,935 | 17,915 | 103,907 | 369,049 | 519,535 | 1,845,245 | 10,702,421 | 53,512,105 |
| -1 | -5 | -29 | -103 | -145 | -515 | -2,987 | -3,583 | -14,935 | -17,915 | -103,907 | -369,049 | -519,535 | -1,845,245 | -10,702,421 | -53,512,105 |
