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 316,356,271, 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 | 316,356,271 | |
| -1 | -316,356,271 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 316,356,271.
Example:
1 x 316,356,271 = 316,356,271
and
-1 x -316,356,271 = 316,356,271
Notice both answers equal 316,356,271
With that explanation out of the way, let's continue. Next, we take the number 316,356,271 and divide it by 2:
316,356,271 ÷ 2 = 158,178,135.5
If the quotient is a whole number, then 2 and 158,178,135.5 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 | 316,356,271 | |
| -1 | -316,356,271 |
Now, we try dividing 316,356,271 by 3:
316,356,271 ÷ 3 = 105,452,090.3333
If the quotient is a whole number, then 3 and 105,452,090.3333 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 | 316,356,271 | |
| -1 | -316,356,271 |
Let's try dividing by 4:
316,356,271 ÷ 4 = 79,089,067.75
If the quotient is a whole number, then 4 and 79,089,067.75 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 | 316,356,271 | |
| -1 | 316,356,271 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 31 | 77 | 217 | 341 | 2,387 | 132,533 | 927,731 | 1,457,863 | 4,108,523 | 10,205,041 | 28,759,661 | 45,193,753 | 316,356,271 |
| -1 | -7 | -11 | -31 | -77 | -217 | -341 | -2,387 | -132,533 | -927,731 | -1,457,863 | -4,108,523 | -10,205,041 | -28,759,661 | -45,193,753 | -316,356,271 |
