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 715,574,335, 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 | 715,574,335 | |
| -1 | -715,574,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 715,574,335.
Example:
1 x 715,574,335 = 715,574,335
and
-1 x -715,574,335 = 715,574,335
Notice both answers equal 715,574,335
With that explanation out of the way, let's continue. Next, we take the number 715,574,335 and divide it by 2:
715,574,335 ÷ 2 = 357,787,167.5
If the quotient is a whole number, then 2 and 357,787,167.5 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 | 715,574,335 | |
| -1 | -715,574,335 |
Now, we try dividing 715,574,335 by 3:
715,574,335 ÷ 3 = 238,524,778.3333
If the quotient is a whole number, then 3 and 238,524,778.3333 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 | 715,574,335 | |
| -1 | -715,574,335 |
Let's try dividing by 4:
715,574,335 ÷ 4 = 178,893,583.75
If the quotient is a whole number, then 4 and 178,893,583.75 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 | 715,574,335 | |
| -1 | 715,574,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 97 | 485 | 679 | 3,395 | 210,773 | 1,053,865 | 1,475,411 | 7,377,055 | 20,444,981 | 102,224,905 | 143,114,867 | 715,574,335 |
| -1 | -5 | -7 | -35 | -97 | -485 | -679 | -3,395 | -210,773 | -1,053,865 | -1,475,411 | -7,377,055 | -20,444,981 | -102,224,905 | -143,114,867 | -715,574,335 |
