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 634,355,435, 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 | 634,355,435 | |
| -1 | -634,355,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 634,355,435.
Example:
1 x 634,355,435 = 634,355,435
and
-1 x -634,355,435 = 634,355,435
Notice both answers equal 634,355,435
With that explanation out of the way, let's continue. Next, we take the number 634,355,435 and divide it by 2:
634,355,435 ÷ 2 = 317,177,717.5
If the quotient is a whole number, then 2 and 317,177,717.5 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 | 634,355,435 | |
| -1 | -634,355,435 |
Now, we try dividing 634,355,435 by 3:
634,355,435 ÷ 3 = 211,451,811.6667
If the quotient is a whole number, then 3 and 211,451,811.6667 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 | 634,355,435 | |
| -1 | -634,355,435 |
Let's try dividing by 4:
634,355,435 ÷ 4 = 158,588,858.75
If the quotient is a whole number, then 4 and 158,588,858.75 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 | 634,355,435 | |
| -1 | 634,355,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,451 | 7,255 | 10,157 | 12,491 | 50,785 | 62,455 | 87,437 | 437,185 | 18,124,441 | 90,622,205 | 126,871,087 | 634,355,435 |
| -1 | -5 | -7 | -35 | -1,451 | -7,255 | -10,157 | -12,491 | -50,785 | -62,455 | -87,437 | -437,185 | -18,124,441 | -90,622,205 | -126,871,087 | -634,355,435 |
