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 730,006,265, 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 | 730,006,265 | |
| -1 | -730,006,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 730,006,265.
Example:
1 x 730,006,265 = 730,006,265
and
-1 x -730,006,265 = 730,006,265
Notice both answers equal 730,006,265
With that explanation out of the way, let's continue. Next, we take the number 730,006,265 and divide it by 2:
730,006,265 ÷ 2 = 365,003,132.5
If the quotient is a whole number, then 2 and 365,003,132.5 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 | 730,006,265 | |
| -1 | -730,006,265 |
Now, we try dividing 730,006,265 by 3:
730,006,265 ÷ 3 = 243,335,421.6667
If the quotient is a whole number, then 3 and 243,335,421.6667 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 | 730,006,265 | |
| -1 | -730,006,265 |
Let's try dividing by 4:
730,006,265 ÷ 4 = 182,501,566.25
If the quotient is a whole number, then 4 and 182,501,566.25 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 | 730,006,265 | |
| -1 | 730,006,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 167 | 835 | 2,839 | 14,195 | 51,427 | 257,135 | 874,259 | 4,371,295 | 8,588,309 | 42,941,545 | 146,001,253 | 730,006,265 |
| -1 | -5 | -17 | -85 | -167 | -835 | -2,839 | -14,195 | -51,427 | -257,135 | -874,259 | -4,371,295 | -8,588,309 | -42,941,545 | -146,001,253 | -730,006,265 |
