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 630,343,655, 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 | 630,343,655 | |
| -1 | -630,343,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 630,343,655.
Example:
1 x 630,343,655 = 630,343,655
and
-1 x -630,343,655 = 630,343,655
Notice both answers equal 630,343,655
With that explanation out of the way, let's continue. Next, we take the number 630,343,655 and divide it by 2:
630,343,655 ÷ 2 = 315,171,827.5
If the quotient is a whole number, then 2 and 315,171,827.5 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 | 630,343,655 | |
| -1 | -630,343,655 |
Now, we try dividing 630,343,655 by 3:
630,343,655 ÷ 3 = 210,114,551.6667
If the quotient is a whole number, then 3 and 210,114,551.6667 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 | 630,343,655 | |
| -1 | -630,343,655 |
Let's try dividing by 4:
630,343,655 ÷ 4 = 157,585,913.75
If the quotient is a whole number, then 4 and 157,585,913.75 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 | 630,343,655 | |
| -1 | 630,343,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 185 | 547 | 2,735 | 6,229 | 20,239 | 31,145 | 101,195 | 230,473 | 1,152,365 | 3,407,263 | 17,036,315 | 126,068,731 | 630,343,655 |
| -1 | -5 | -37 | -185 | -547 | -2,735 | -6,229 | -20,239 | -31,145 | -101,195 | -230,473 | -1,152,365 | -3,407,263 | -17,036,315 | -126,068,731 | -630,343,655 |
