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 405,730,007, 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 | 405,730,007 | |
| -1 | -405,730,007 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 405,730,007.
Example:
1 x 405,730,007 = 405,730,007
and
-1 x -405,730,007 = 405,730,007
Notice both answers equal 405,730,007
With that explanation out of the way, let's continue. Next, we take the number 405,730,007 and divide it by 2:
405,730,007 ÷ 2 = 202,865,003.5
If the quotient is a whole number, then 2 and 202,865,003.5 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 | 405,730,007 | |
| -1 | -405,730,007 |
Now, we try dividing 405,730,007 by 3:
405,730,007 ÷ 3 = 135,243,335.6667
If the quotient is a whole number, then 3 and 135,243,335.6667 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 | 405,730,007 | |
| -1 | -405,730,007 |
Let's try dividing by 4:
405,730,007 ÷ 4 = 101,432,501.75
If the quotient is a whole number, then 4 and 101,432,501.75 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 | 405,730,007 | |
| -1 | 405,730,007 |
If you did it right, you will end up with this table:
| 1 | 17 | 167 | 241 | 593 | 2,839 | 4,097 | 10,081 | 40,247 | 99,031 | 142,913 | 684,199 | 1,683,527 | 2,429,521 | 23,866,471 | 405,730,007 |
| -1 | -17 | -167 | -241 | -593 | -2,839 | -4,097 | -10,081 | -40,247 | -99,031 | -142,913 | -684,199 | -1,683,527 | -2,429,521 | -23,866,471 | -405,730,007 |
