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 630,753,097, 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 | 630,753,097 | |
| -1 | -630,753,097 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 630,753,097.
Example:
1 x 630,753,097 = 630,753,097
and
-1 x -630,753,097 = 630,753,097
Notice both answers equal 630,753,097
With that explanation out of the way, let's continue. Next, we take the number 630,753,097 and divide it by 2:
630,753,097 ÷ 2 = 315,376,548.5
If the quotient is a whole number, then 2 and 315,376,548.5 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 | 630,753,097 | |
| -1 | -630,753,097 |
Now, we try dividing 630,753,097 by 3:
630,753,097 ÷ 3 = 210,251,032.3333
If the quotient is a whole number, then 3 and 210,251,032.3333 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 | 630,753,097 | |
| -1 | -630,753,097 |
Let's try dividing by 4:
630,753,097 ÷ 4 = 157,688,274.25
If the quotient is a whole number, then 4 and 157,688,274.25 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 | 630,753,097 | |
| -1 | 630,753,097 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 481 | 733 | 1,789 | 9,529 | 23,257 | 27,121 | 66,193 | 352,573 | 860,509 | 1,311,337 | 17,047,381 | 48,519,469 | 630,753,097 |
| -1 | -13 | -37 | -481 | -733 | -1,789 | -9,529 | -23,257 | -27,121 | -66,193 | -352,573 | -860,509 | -1,311,337 | -17,047,381 | -48,519,469 | -630,753,097 |
