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 630,731,101, 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 | 630,731,101 | |
| -1 | -630,731,101 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 630,731,101.
Example:
1 x 630,731,101 = 630,731,101
and
-1 x -630,731,101 = 630,731,101
Notice both answers equal 630,731,101
With that explanation out of the way, let's continue. Next, we take the number 630,731,101 and divide it by 2:
630,731,101 ÷ 2 = 315,365,550.5
If the quotient is a whole number, then 2 and 315,365,550.5 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 | 630,731,101 | |
| -1 | -630,731,101 |
Now, we try dividing 630,731,101 by 3:
630,731,101 ÷ 3 = 210,243,700.3333
If the quotient is a whole number, then 3 and 210,243,700.3333 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 | 630,731,101 | |
| -1 | -630,731,101 |
Let's try dividing by 4:
630,731,101 ÷ 4 = 157,682,775.25
If the quotient is a whole number, then 4 and 157,682,775.25 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 | 630,731,101 | |
| -1 | 630,731,101 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 1,001 | 630,101 | 4,410,707 | 6,931,111 | 8,191,313 | 48,517,777 | 57,339,191 | 90,104,443 | 630,731,101 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -1,001 | -630,101 | -4,410,707 | -6,931,111 | -8,191,313 | -48,517,777 | -57,339,191 | -90,104,443 | -630,731,101 |
