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 245,033,135, 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 | 245,033,135 | |
| -1 | -245,033,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 245,033,135.
Example:
1 x 245,033,135 = 245,033,135
and
-1 x -245,033,135 = 245,033,135
Notice both answers equal 245,033,135
With that explanation out of the way, let's continue. Next, we take the number 245,033,135 and divide it by 2:
245,033,135 ÷ 2 = 122,516,567.5
If the quotient is a whole number, then 2 and 122,516,567.5 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 | 245,033,135 | |
| -1 | -245,033,135 |
Now, we try dividing 245,033,135 by 3:
245,033,135 ÷ 3 = 81,677,711.6667
If the quotient is a whole number, then 3 and 81,677,711.6667 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 | 245,033,135 | |
| -1 | -245,033,135 |
Let's try dividing by 4:
245,033,135 ÷ 4 = 61,258,283.75
If the quotient is a whole number, then 4 and 61,258,283.75 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 | 245,033,135 | |
| -1 | 245,033,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 215 | 241 | 1,205 | 4,729 | 10,363 | 23,645 | 51,815 | 203,347 | 1,016,735 | 1,139,689 | 5,698,445 | 49,006,627 | 245,033,135 |
| -1 | -5 | -43 | -215 | -241 | -1,205 | -4,729 | -10,363 | -23,645 | -51,815 | -203,347 | -1,016,735 | -1,139,689 | -5,698,445 | -49,006,627 | -245,033,135 |
