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 633,854,075, 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 | 633,854,075 | |
| -1 | -633,854,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 633,854,075.
Example:
1 x 633,854,075 = 633,854,075
and
-1 x -633,854,075 = 633,854,075
Notice both answers equal 633,854,075
With that explanation out of the way, let's continue. Next, we take the number 633,854,075 and divide it by 2:
633,854,075 ÷ 2 = 316,927,037.5
If the quotient is a whole number, then 2 and 316,927,037.5 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 | 633,854,075 | |
| -1 | -633,854,075 |
Now, we try dividing 633,854,075 by 3:
633,854,075 ÷ 3 = 211,284,691.6667
If the quotient is a whole number, then 3 and 211,284,691.6667 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 | 633,854,075 | |
| -1 | -633,854,075 |
Let's try dividing by 4:
633,854,075 ÷ 4 = 158,463,518.75
If the quotient is a whole number, then 4 and 158,463,518.75 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 | 633,854,075 | |
| -1 | 633,854,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 109 | 545 | 2,725 | 232,607 | 1,163,035 | 5,815,175 | 25,354,163 | 126,770,815 | 633,854,075 |
| -1 | -5 | -25 | -109 | -545 | -2,725 | -232,607 | -1,163,035 | -5,815,175 | -25,354,163 | -126,770,815 | -633,854,075 |
