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 650,567,245, 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 | 650,567,245 | |
| -1 | -650,567,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 650,567,245.
Example:
1 x 650,567,245 = 650,567,245
and
-1 x -650,567,245 = 650,567,245
Notice both answers equal 650,567,245
With that explanation out of the way, let's continue. Next, we take the number 650,567,245 and divide it by 2:
650,567,245 ÷ 2 = 325,283,622.5
If the quotient is a whole number, then 2 and 325,283,622.5 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 | 650,567,245 | |
| -1 | -650,567,245 |
Now, we try dividing 650,567,245 by 3:
650,567,245 ÷ 3 = 216,855,748.3333
If the quotient is a whole number, then 3 and 216,855,748.3333 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 | 650,567,245 | |
| -1 | -650,567,245 |
Let's try dividing by 4:
650,567,245 ÷ 4 = 162,641,811.25
If the quotient is a whole number, then 4 and 162,641,811.25 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 | 650,567,245 | |
| -1 | 650,567,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 227 | 229 | 1,135 | 1,145 | 2,503 | 12,515 | 51,983 | 259,915 | 568,181 | 573,187 | 2,840,905 | 2,865,935 | 130,113,449 | 650,567,245 |
| -1 | -5 | -227 | -229 | -1,135 | -1,145 | -2,503 | -12,515 | -51,983 | -259,915 | -568,181 | -573,187 | -2,840,905 | -2,865,935 | -130,113,449 | -650,567,245 |
