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 612,366,001, 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 | 612,366,001 | |
| -1 | -612,366,001 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 612,366,001.
Example:
1 x 612,366,001 = 612,366,001
and
-1 x -612,366,001 = 612,366,001
Notice both answers equal 612,366,001
With that explanation out of the way, let's continue. Next, we take the number 612,366,001 and divide it by 2:
612,366,001 ÷ 2 = 306,183,000.5
If the quotient is a whole number, then 2 and 306,183,000.5 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 | 612,366,001 | |
| -1 | -612,366,001 |
Now, we try dividing 612,366,001 by 3:
612,366,001 ÷ 3 = 204,122,000.3333
If the quotient is a whole number, then 3 and 204,122,000.3333 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 | 612,366,001 | |
| -1 | -612,366,001 |
Let's try dividing by 4:
612,366,001 ÷ 4 = 153,091,500.25
If the quotient is a whole number, then 4 and 153,091,500.25 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 | 612,366,001 | |
| -1 | 612,366,001 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 377 | 911 | 1,783 | 11,843 | 23,179 | 26,419 | 51,707 | 343,447 | 672,191 | 1,624,313 | 21,116,069 | 47,105,077 | 612,366,001 |
| -1 | -13 | -29 | -377 | -911 | -1,783 | -11,843 | -23,179 | -26,419 | -51,707 | -343,447 | -672,191 | -1,624,313 | -21,116,069 | -47,105,077 | -612,366,001 |
