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 634,061,635, 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 | 634,061,635 | |
| -1 | -634,061,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 634,061,635.
Example:
1 x 634,061,635 = 634,061,635
and
-1 x -634,061,635 = 634,061,635
Notice both answers equal 634,061,635
With that explanation out of the way, let's continue. Next, we take the number 634,061,635 and divide it by 2:
634,061,635 ÷ 2 = 317,030,817.5
If the quotient is a whole number, then 2 and 317,030,817.5 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 | 634,061,635 | |
| -1 | -634,061,635 |
Now, we try dividing 634,061,635 by 3:
634,061,635 ÷ 3 = 211,353,878.3333
If the quotient is a whole number, then 3 and 211,353,878.3333 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 | 634,061,635 | |
| -1 | -634,061,635 |
Let's try dividing by 4:
634,061,635 ÷ 4 = 158,515,408.75
If the quotient is a whole number, then 4 and 158,515,408.75 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 | 634,061,635 | |
| -1 | 634,061,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 1,987 | 3,359 | 9,935 | 16,795 | 37,753 | 63,821 | 188,765 | 319,105 | 6,674,333 | 33,371,665 | 126,812,327 | 634,061,635 |
| -1 | -5 | -19 | -95 | -1,987 | -3,359 | -9,935 | -16,795 | -37,753 | -63,821 | -188,765 | -319,105 | -6,674,333 | -33,371,665 | -126,812,327 | -634,061,635 |
