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 133,153,355, 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 | 133,153,355 | |
| -1 | -133,153,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,153,355.
Example:
1 x 133,153,355 = 133,153,355
and
-1 x -133,153,355 = 133,153,355
Notice both answers equal 133,153,355
With that explanation out of the way, let's continue. Next, we take the number 133,153,355 and divide it by 2:
133,153,355 ÷ 2 = 66,576,677.5
If the quotient is a whole number, then 2 and 66,576,677.5 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 | 133,153,355 | |
| -1 | -133,153,355 |
Now, we try dividing 133,153,355 by 3:
133,153,355 ÷ 3 = 44,384,451.6667
If the quotient is a whole number, then 3 and 44,384,451.6667 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 | 133,153,355 | |
| -1 | -133,153,355 |
Let's try dividing by 4:
133,153,355 ÷ 4 = 33,288,338.75
If the quotient is a whole number, then 4 and 33,288,338.75 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 | 133,153,355 | |
| -1 | 133,153,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 97 | 145 | 485 | 2,813 | 9,467 | 14,065 | 47,335 | 274,543 | 918,299 | 1,372,715 | 4,591,495 | 26,630,671 | 133,153,355 |
| -1 | -5 | -29 | -97 | -145 | -485 | -2,813 | -9,467 | -14,065 | -47,335 | -274,543 | -918,299 | -1,372,715 | -4,591,495 | -26,630,671 | -133,153,355 |
