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 53,166,533, 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 | 53,166,533 | |
| -1 | -53,166,533 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,166,533.
Example:
1 x 53,166,533 = 53,166,533
and
-1 x -53,166,533 = 53,166,533
Notice both answers equal 53,166,533
With that explanation out of the way, let's continue. Next, we take the number 53,166,533 and divide it by 2:
53,166,533 ÷ 2 = 26,583,266.5
If the quotient is a whole number, then 2 and 26,583,266.5 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 | 53,166,533 | |
| -1 | -53,166,533 |
Now, we try dividing 53,166,533 by 3:
53,166,533 ÷ 3 = 17,722,177.6667
If the quotient is a whole number, then 3 and 17,722,177.6667 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 | 53,166,533 | |
| -1 | -53,166,533 |
Let's try dividing by 4:
53,166,533 ÷ 4 = 13,291,633.25
If the quotient is a whole number, then 4 and 13,291,633.25 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 | 53,166,533 | |
| -1 | 53,166,533 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 173 | 301 | 1,021 | 1,211 | 7,147 | 7,439 | 43,903 | 52,073 | 176,633 | 307,321 | 1,236,431 | 7,595,219 | 53,166,533 |
| -1 | -7 | -43 | -173 | -301 | -1,021 | -1,211 | -7,147 | -7,439 | -43,903 | -52,073 | -176,633 | -307,321 | -1,236,431 | -7,595,219 | -53,166,533 |
