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 630,201,523, 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 | 630,201,523 | |
| -1 | -630,201,523 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 630,201,523.
Example:
1 x 630,201,523 = 630,201,523
and
-1 x -630,201,523 = 630,201,523
Notice both answers equal 630,201,523
With that explanation out of the way, let's continue. Next, we take the number 630,201,523 and divide it by 2:
630,201,523 ÷ 2 = 315,100,761.5
If the quotient is a whole number, then 2 and 315,100,761.5 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 | 630,201,523 | |
| -1 | -630,201,523 |
Now, we try dividing 630,201,523 by 3:
630,201,523 ÷ 3 = 210,067,174.3333
If the quotient is a whole number, then 3 and 210,067,174.3333 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 | 630,201,523 | |
| -1 | -630,201,523 |
Let's try dividing by 4:
630,201,523 ÷ 4 = 157,550,380.75
If the quotient is a whole number, then 4 and 157,550,380.75 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 | 630,201,523 | |
| -1 | 630,201,523 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 203 | 1,361 | 2,281 | 9,527 | 15,967 | 39,469 | 66,149 | 276,283 | 463,043 | 3,104,441 | 21,731,087 | 90,028,789 | 630,201,523 |
| -1 | -7 | -29 | -203 | -1,361 | -2,281 | -9,527 | -15,967 | -39,469 | -66,149 | -276,283 | -463,043 | -3,104,441 | -21,731,087 | -90,028,789 | -630,201,523 |
