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 133,355,453, 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 | 133,355,453 | |
| -1 | -133,355,453 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,355,453.
Example:
1 x 133,355,453 = 133,355,453
and
-1 x -133,355,453 = 133,355,453
Notice both answers equal 133,355,453
With that explanation out of the way, let's continue. Next, we take the number 133,355,453 and divide it by 2:
133,355,453 ÷ 2 = 66,677,726.5
If the quotient is a whole number, then 2 and 66,677,726.5 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 | 133,355,453 | |
| -1 | -133,355,453 |
Now, we try dividing 133,355,453 by 3:
133,355,453 ÷ 3 = 44,451,817.6667
If the quotient is a whole number, then 3 and 44,451,817.6667 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 | 133,355,453 | |
| -1 | -133,355,453 |
Let's try dividing by 4:
133,355,453 ÷ 4 = 33,338,863.25
If the quotient is a whole number, then 4 and 33,338,863.25 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 | 133,355,453 | |
| -1 | 133,355,453 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 233 | 1,631 | 2,563 | 7,433 | 17,941 | 52,031 | 81,763 | 572,341 | 1,731,889 | 12,123,223 | 19,050,779 | 133,355,453 |
| -1 | -7 | -11 | -77 | -233 | -1,631 | -2,563 | -7,433 | -17,941 | -52,031 | -81,763 | -572,341 | -1,731,889 | -12,123,223 | -19,050,779 | -133,355,453 |
