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 133,675,069, 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 | 133,675,069 | |
| -1 | -133,675,069 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,675,069.
Example:
1 x 133,675,069 = 133,675,069
and
-1 x -133,675,069 = 133,675,069
Notice both answers equal 133,675,069
With that explanation out of the way, let's continue. Next, we take the number 133,675,069 and divide it by 2:
133,675,069 ÷ 2 = 66,837,534.5
If the quotient is a whole number, then 2 and 66,837,534.5 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 | 133,675,069 | |
| -1 | -133,675,069 |
Now, we try dividing 133,675,069 by 3:
133,675,069 ÷ 3 = 44,558,356.3333
If the quotient is a whole number, then 3 and 44,558,356.3333 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 | 133,675,069 | |
| -1 | -133,675,069 |
Let's try dividing by 4:
133,675,069 ÷ 4 = 33,418,767.25
If the quotient is a whole number, then 4 and 33,418,767.25 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 | 133,675,069 | |
| -1 | 133,675,069 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 83 | 341 | 913 | 2,573 | 4,723 | 28,303 | 51,953 | 146,413 | 392,009 | 1,610,543 | 4,312,099 | 12,152,279 | 133,675,069 |
| -1 | -11 | -31 | -83 | -341 | -913 | -2,573 | -4,723 | -28,303 | -51,953 | -146,413 | -392,009 | -1,610,543 | -4,312,099 | -12,152,279 | -133,675,069 |
