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 732,645,719, 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 | 732,645,719 | |
| -1 | -732,645,719 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 732,645,719.
Example:
1 x 732,645,719 = 732,645,719
and
-1 x -732,645,719 = 732,645,719
Notice both answers equal 732,645,719
With that explanation out of the way, let's continue. Next, we take the number 732,645,719 and divide it by 2:
732,645,719 ÷ 2 = 366,322,859.5
If the quotient is a whole number, then 2 and 366,322,859.5 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 | 732,645,719 | |
| -1 | -732,645,719 |
Now, we try dividing 732,645,719 by 3:
732,645,719 ÷ 3 = 244,215,239.6667
If the quotient is a whole number, then 3 and 244,215,239.6667 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 | 732,645,719 | |
| -1 | -732,645,719 |
Let's try dividing by 4:
732,645,719 ÷ 4 = 183,161,429.75
If the quotient is a whole number, then 4 and 183,161,429.75 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 | 732,645,719 | |
| -1 | 732,645,719 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 19 | 221 | 247 | 323 | 4,199 | 174,481 | 2,268,253 | 2,966,177 | 3,315,139 | 38,560,301 | 43,096,807 | 56,357,363 | 732,645,719 |
| -1 | -13 | -17 | -19 | -221 | -247 | -323 | -4,199 | -174,481 | -2,268,253 | -2,966,177 | -3,315,139 | -38,560,301 | -43,096,807 | -56,357,363 | -732,645,719 |
