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 316,758,743, 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 | 316,758,743 | |
| -1 | -316,758,743 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 316,758,743.
Example:
1 x 316,758,743 = 316,758,743
and
-1 x -316,758,743 = 316,758,743
Notice both answers equal 316,758,743
With that explanation out of the way, let's continue. Next, we take the number 316,758,743 and divide it by 2:
316,758,743 ÷ 2 = 158,379,371.5
If the quotient is a whole number, then 2 and 158,379,371.5 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 | 316,758,743 | |
| -1 | -316,758,743 |
Now, we try dividing 316,758,743 by 3:
316,758,743 ÷ 3 = 105,586,247.6667
If the quotient is a whole number, then 3 and 105,586,247.6667 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 | 316,758,743 | |
| -1 | -316,758,743 |
Let's try dividing by 4:
316,758,743 ÷ 4 = 79,189,685.75
If the quotient is a whole number, then 4 and 79,189,685.75 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 | 316,758,743 | |
| -1 | 316,758,743 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 89 | 287 | 623 | 3,649 | 12,401 | 25,543 | 86,807 | 508,441 | 1,103,689 | 3,559,087 | 7,725,823 | 45,251,249 | 316,758,743 |
| -1 | -7 | -41 | -89 | -287 | -623 | -3,649 | -12,401 | -25,543 | -86,807 | -508,441 | -1,103,689 | -3,559,087 | -7,725,823 | -45,251,249 | -316,758,743 |
