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 713,013,763, 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 | 713,013,763 | |
| -1 | -713,013,763 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 713,013,763.
Example:
1 x 713,013,763 = 713,013,763
and
-1 x -713,013,763 = 713,013,763
Notice both answers equal 713,013,763
With that explanation out of the way, let's continue. Next, we take the number 713,013,763 and divide it by 2:
713,013,763 ÷ 2 = 356,506,881.5
If the quotient is a whole number, then 2 and 356,506,881.5 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 | 713,013,763 | |
| -1 | -713,013,763 |
Now, we try dividing 713,013,763 by 3:
713,013,763 ÷ 3 = 237,671,254.3333
If the quotient is a whole number, then 3 and 237,671,254.3333 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 | 713,013,763 | |
| -1 | -713,013,763 |
Let's try dividing by 4:
713,013,763 ÷ 4 = 178,253,440.75
If the quotient is a whole number, then 4 and 178,253,440.75 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 | 713,013,763 | |
| -1 | 713,013,763 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 827 | 5,789 | 9,097 | 11,197 | 63,679 | 78,379 | 123,167 | 862,169 | 9,259,919 | 64,819,433 | 101,859,109 | 713,013,763 |
| -1 | -7 | -11 | -77 | -827 | -5,789 | -9,097 | -11,197 | -63,679 | -78,379 | -123,167 | -862,169 | -9,259,919 | -64,819,433 | -101,859,109 | -713,013,763 |
