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 612,106,033, 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 | 612,106,033 | |
| -1 | -612,106,033 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 612,106,033.
Example:
1 x 612,106,033 = 612,106,033
and
-1 x -612,106,033 = 612,106,033
Notice both answers equal 612,106,033
With that explanation out of the way, let's continue. Next, we take the number 612,106,033 and divide it by 2:
612,106,033 ÷ 2 = 306,053,016.5
If the quotient is a whole number, then 2 and 306,053,016.5 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 | 612,106,033 | |
| -1 | -612,106,033 |
Now, we try dividing 612,106,033 by 3:
612,106,033 ÷ 3 = 204,035,344.3333
If the quotient is a whole number, then 3 and 204,035,344.3333 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 | 612,106,033 | |
| -1 | -612,106,033 |
Let's try dividing by 4:
612,106,033 ÷ 4 = 153,026,508.25
If the quotient is a whole number, then 4 and 153,026,508.25 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 | 612,106,033 | |
| -1 | 612,106,033 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 19 | 77 | 133 | 209 | 1,463 | 418,391 | 2,928,737 | 4,602,301 | 7,949,429 | 32,216,107 | 55,646,003 | 87,443,719 | 612,106,033 |
| -1 | -7 | -11 | -19 | -77 | -133 | -209 | -1,463 | -418,391 | -2,928,737 | -4,602,301 | -7,949,429 | -32,216,107 | -55,646,003 | -87,443,719 | -612,106,033 |
