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 53,121,011, 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 | 53,121,011 | |
| -1 | -53,121,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,121,011.
Example:
1 x 53,121,011 = 53,121,011
and
-1 x -53,121,011 = 53,121,011
Notice both answers equal 53,121,011
With that explanation out of the way, let's continue. Next, we take the number 53,121,011 and divide it by 2:
53,121,011 ÷ 2 = 26,560,505.5
If the quotient is a whole number, then 2 and 26,560,505.5 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 | 53,121,011 | |
| -1 | -53,121,011 |
Now, we try dividing 53,121,011 by 3:
53,121,011 ÷ 3 = 17,707,003.6667
If the quotient is a whole number, then 3 and 17,707,003.6667 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 | 53,121,011 | |
| -1 | -53,121,011 |
Let's try dividing by 4:
53,121,011 ÷ 4 = 13,280,252.75
If the quotient is a whole number, then 4 and 13,280,252.75 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 | 53,121,011 | |
| -1 | 53,121,011 |
If you did it right, you will end up with this table:
| 1 | 29 | 31 | 37 | 899 | 1,073 | 1,147 | 1,597 | 33,263 | 46,313 | 49,507 | 59,089 | 1,435,703 | 1,713,581 | 1,831,759 | 53,121,011 |
| -1 | -29 | -31 | -37 | -899 | -1,073 | -1,147 | -1,597 | -33,263 | -46,313 | -49,507 | -59,089 | -1,435,703 | -1,713,581 | -1,831,759 | -53,121,011 |
