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 713,015,755, 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 | 713,015,755 | |
| -1 | -713,015,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 713,015,755.
Example:
1 x 713,015,755 = 713,015,755
and
-1 x -713,015,755 = 713,015,755
Notice both answers equal 713,015,755
With that explanation out of the way, let's continue. Next, we take the number 713,015,755 and divide it by 2:
713,015,755 ÷ 2 = 356,507,877.5
If the quotient is a whole number, then 2 and 356,507,877.5 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 | 713,015,755 | |
| -1 | -713,015,755 |
Now, we try dividing 713,015,755 by 3:
713,015,755 ÷ 3 = 237,671,918.3333
If the quotient is a whole number, then 3 and 237,671,918.3333 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 | 713,015,755 | |
| -1 | -713,015,755 |
Let's try dividing by 4:
713,015,755 ÷ 4 = 178,253,938.75
If the quotient is a whole number, then 4 and 178,253,938.75 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 | 713,015,755 | |
| -1 | 713,015,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 23 | 95 | 115 | 437 | 2,185 | 326,323 | 1,631,615 | 6,200,137 | 7,505,429 | 31,000,685 | 37,527,145 | 142,603,151 | 713,015,755 |
| -1 | -5 | -19 | -23 | -95 | -115 | -437 | -2,185 | -326,323 | -1,631,615 | -6,200,137 | -7,505,429 | -31,000,685 | -37,527,145 | -142,603,151 | -713,015,755 |
