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 313,717,355, 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 | 313,717,355 | |
| -1 | -313,717,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 313,717,355.
Example:
1 x 313,717,355 = 313,717,355
and
-1 x -313,717,355 = 313,717,355
Notice both answers equal 313,717,355
With that explanation out of the way, let's continue. Next, we take the number 313,717,355 and divide it by 2:
313,717,355 ÷ 2 = 156,858,677.5
If the quotient is a whole number, then 2 and 156,858,677.5 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 | 313,717,355 | |
| -1 | -313,717,355 |
Now, we try dividing 313,717,355 by 3:
313,717,355 ÷ 3 = 104,572,451.6667
If the quotient is a whole number, then 3 and 104,572,451.6667 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 | 313,717,355 | |
| -1 | -313,717,355 |
Let's try dividing by 4:
313,717,355 ÷ 4 = 78,429,338.75
If the quotient is a whole number, then 4 and 78,429,338.75 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 | 313,717,355 | |
| -1 | 313,717,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 49 | 115 | 161 | 245 | 805 | 1,127 | 5,635 | 55,673 | 278,365 | 389,711 | 1,280,479 | 1,948,555 | 2,727,977 | 6,402,395 | 8,963,353 | 13,639,885 | 44,816,765 | 62,743,471 | 313,717,355 |
| -1 | -5 | -7 | -23 | -35 | -49 | -115 | -161 | -245 | -805 | -1,127 | -5,635 | -55,673 | -278,365 | -389,711 | -1,280,479 | -1,948,555 | -2,727,977 | -6,402,395 | -8,963,353 | -13,639,885 | -44,816,765 | -62,743,471 | -313,717,355 |
