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 650,224,271, 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 | 650,224,271 | |
| -1 | -650,224,271 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 650,224,271.
Example:
1 x 650,224,271 = 650,224,271
and
-1 x -650,224,271 = 650,224,271
Notice both answers equal 650,224,271
With that explanation out of the way, let's continue. Next, we take the number 650,224,271 and divide it by 2:
650,224,271 ÷ 2 = 325,112,135.5
If the quotient is a whole number, then 2 and 325,112,135.5 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 | 650,224,271 | |
| -1 | -650,224,271 |
Now, we try dividing 650,224,271 by 3:
650,224,271 ÷ 3 = 216,741,423.6667
If the quotient is a whole number, then 3 and 216,741,423.6667 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 | 650,224,271 | |
| -1 | -650,224,271 |
Let's try dividing by 4:
650,224,271 ÷ 4 = 162,556,067.75
If the quotient is a whole number, then 4 and 162,556,067.75 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 | 650,224,271 | |
| -1 | 650,224,271 |
If you did it right, you will end up with this table:
| 1 | 97 | 103 | 151 | 431 | 9,991 | 14,647 | 15,553 | 41,807 | 44,393 | 65,081 | 1,508,641 | 4,306,121 | 6,312,857 | 6,703,343 | 650,224,271 |
| -1 | -97 | -103 | -151 | -431 | -9,991 | -14,647 | -15,553 | -41,807 | -44,393 | -65,081 | -1,508,641 | -4,306,121 | -6,312,857 | -6,703,343 | -650,224,271 |
