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 316,775,701, 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 | 316,775,701 | |
| -1 | -316,775,701 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 316,775,701.
Example:
1 x 316,775,701 = 316,775,701
and
-1 x -316,775,701 = 316,775,701
Notice both answers equal 316,775,701
With that explanation out of the way, let's continue. Next, we take the number 316,775,701 and divide it by 2:
316,775,701 ÷ 2 = 158,387,850.5
If the quotient is a whole number, then 2 and 158,387,850.5 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 | 316,775,701 | |
| -1 | -316,775,701 |
Now, we try dividing 316,775,701 by 3:
316,775,701 ÷ 3 = 105,591,900.3333
If the quotient is a whole number, then 3 and 105,591,900.3333 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 | 316,775,701 | |
| -1 | -316,775,701 |
Let's try dividing by 4:
316,775,701 ÷ 4 = 79,193,925.25
If the quotient is a whole number, then 4 and 79,193,925.25 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 | 316,775,701 | |
| -1 | 316,775,701 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 79 | 121 | 341 | 869 | 1,069 | 2,449 | 3,751 | 9,559 | 11,759 | 26,939 | 33,139 | 84,451 | 129,349 | 296,329 | 364,529 | 928,961 | 2,617,981 | 4,009,819 | 10,218,571 | 28,797,791 | 316,775,701 |
| -1 | -11 | -31 | -79 | -121 | -341 | -869 | -1,069 | -2,449 | -3,751 | -9,559 | -11,759 | -26,939 | -33,139 | -84,451 | -129,349 | -296,329 | -364,529 | -928,961 | -2,617,981 | -4,009,819 | -10,218,571 | -28,797,791 | -316,775,701 |
