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 634,024,115, 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 | 634,024,115 | |
| -1 | -634,024,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 634,024,115.
Example:
1 x 634,024,115 = 634,024,115
and
-1 x -634,024,115 = 634,024,115
Notice both answers equal 634,024,115
With that explanation out of the way, let's continue. Next, we take the number 634,024,115 and divide it by 2:
634,024,115 ÷ 2 = 317,012,057.5
If the quotient is a whole number, then 2 and 317,012,057.5 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 | 634,024,115 | |
| -1 | -634,024,115 |
Now, we try dividing 634,024,115 by 3:
634,024,115 ÷ 3 = 211,341,371.6667
If the quotient is a whole number, then 3 and 211,341,371.6667 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 | 634,024,115 | |
| -1 | -634,024,115 |
Let's try dividing by 4:
634,024,115 ÷ 4 = 158,506,028.75
If the quotient is a whole number, then 4 and 158,506,028.75 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 | 634,024,115 | |
| -1 | 634,024,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 109 | 545 | 911 | 1,277 | 4,555 | 6,385 | 99,299 | 139,193 | 496,495 | 695,965 | 1,163,347 | 5,816,735 | 126,804,823 | 634,024,115 |
| -1 | -5 | -109 | -545 | -911 | -1,277 | -4,555 | -6,385 | -99,299 | -139,193 | -496,495 | -695,965 | -1,163,347 | -5,816,735 | -126,804,823 | -634,024,115 |
