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 651,003,569, 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 | 651,003,569 | |
| -1 | -651,003,569 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 651,003,569.
Example:
1 x 651,003,569 = 651,003,569
and
-1 x -651,003,569 = 651,003,569
Notice both answers equal 651,003,569
With that explanation out of the way, let's continue. Next, we take the number 651,003,569 and divide it by 2:
651,003,569 ÷ 2 = 325,501,784.5
If the quotient is a whole number, then 2 and 325,501,784.5 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 | 651,003,569 | |
| -1 | -651,003,569 |
Now, we try dividing 651,003,569 by 3:
651,003,569 ÷ 3 = 217,001,189.6667
If the quotient is a whole number, then 3 and 217,001,189.6667 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 | 651,003,569 | |
| -1 | -651,003,569 |
Let's try dividing by 4:
651,003,569 ÷ 4 = 162,750,892.25
If the quotient is a whole number, then 4 and 162,750,892.25 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 | 651,003,569 | |
| -1 | 651,003,569 |
If you did it right, you will end up with this table:
| 1 | 23 | 97 | 103 | 2,231 | 2,369 | 2,833 | 9,991 | 65,159 | 229,793 | 274,801 | 291,799 | 6,320,423 | 6,711,377 | 28,304,503 | 651,003,569 |
| -1 | -23 | -97 | -103 | -2,231 | -2,369 | -2,833 | -9,991 | -65,159 | -229,793 | -274,801 | -291,799 | -6,320,423 | -6,711,377 | -28,304,503 | -651,003,569 |
