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 630,630,235, 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 | 630,630,235 | |
| -1 | -630,630,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 630,630,235.
Example:
1 x 630,630,235 = 630,630,235
and
-1 x -630,630,235 = 630,630,235
Notice both answers equal 630,630,235
With that explanation out of the way, let's continue. Next, we take the number 630,630,235 and divide it by 2:
630,630,235 ÷ 2 = 315,315,117.5
If the quotient is a whole number, then 2 and 315,315,117.5 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 | 630,630,235 | |
| -1 | -630,630,235 |
Now, we try dividing 630,630,235 by 3:
630,630,235 ÷ 3 = 210,210,078.3333
If the quotient is a whole number, then 3 and 210,210,078.3333 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 | 630,630,235 | |
| -1 | -630,630,235 |
Let's try dividing by 4:
630,630,235 ÷ 4 = 157,657,558.75
If the quotient is a whole number, then 4 and 157,657,558.75 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 | 630,630,235 | |
| -1 | 630,630,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 797 | 3,985 | 8,329 | 15,143 | 41,645 | 75,715 | 158,251 | 791,255 | 6,638,213 | 33,191,065 | 126,126,047 | 630,630,235 |
| -1 | -5 | -19 | -95 | -797 | -3,985 | -8,329 | -15,143 | -41,645 | -75,715 | -158,251 | -791,255 | -6,638,213 | -33,191,065 | -126,126,047 | -630,630,235 |
