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 732,464,221, 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 | 732,464,221 | |
| -1 | -732,464,221 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 732,464,221.
Example:
1 x 732,464,221 = 732,464,221
and
-1 x -732,464,221 = 732,464,221
Notice both answers equal 732,464,221
With that explanation out of the way, let's continue. Next, we take the number 732,464,221 and divide it by 2:
732,464,221 ÷ 2 = 366,232,110.5
If the quotient is a whole number, then 2 and 366,232,110.5 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 | 732,464,221 | |
| -1 | -732,464,221 |
Now, we try dividing 732,464,221 by 3:
732,464,221 ÷ 3 = 244,154,740.3333
If the quotient is a whole number, then 3 and 244,154,740.3333 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 | 732,464,221 | |
| -1 | -732,464,221 |
Let's try dividing by 4:
732,464,221 ÷ 4 = 183,116,055.25
If the quotient is a whole number, then 4 and 183,116,055.25 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 | 732,464,221 | |
| -1 | 732,464,221 |
If you did it right, you will end up with this table:
| 1 | 41 | 79 | 101 | 2,239 | 3,239 | 4,141 | 7,979 | 91,799 | 176,881 | 226,139 | 327,139 | 7,252,121 | 9,271,699 | 17,864,981 | 732,464,221 |
| -1 | -41 | -79 | -101 | -2,239 | -3,239 | -4,141 | -7,979 | -91,799 | -176,881 | -226,139 | -327,139 | -7,252,121 | -9,271,699 | -17,864,981 | -732,464,221 |
