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 650,472,463, 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 | 650,472,463 | |
| -1 | -650,472,463 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 650,472,463.
Example:
1 x 650,472,463 = 650,472,463
and
-1 x -650,472,463 = 650,472,463
Notice both answers equal 650,472,463
With that explanation out of the way, let's continue. Next, we take the number 650,472,463 and divide it by 2:
650,472,463 ÷ 2 = 325,236,231.5
If the quotient is a whole number, then 2 and 325,236,231.5 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 | 650,472,463 | |
| -1 | -650,472,463 |
Now, we try dividing 650,472,463 by 3:
650,472,463 ÷ 3 = 216,824,154.3333
If the quotient is a whole number, then 3 and 216,824,154.3333 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 | 650,472,463 | |
| -1 | -650,472,463 |
Let's try dividing by 4:
650,472,463 ÷ 4 = 162,618,115.75
If the quotient is a whole number, then 4 and 162,618,115.75 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 | 650,472,463 | |
| -1 | 650,472,463 |
If you did it right, you will end up with this table:
| 1 | 59 | 61 | 149 | 1,213 | 3,599 | 8,791 | 9,089 | 71,567 | 73,993 | 180,737 | 536,251 | 4,365,587 | 10,663,483 | 11,024,957 | 650,472,463 |
| -1 | -59 | -61 | -149 | -1,213 | -3,599 | -8,791 | -9,089 | -71,567 | -73,993 | -180,737 | -536,251 | -4,365,587 | -10,663,483 | -11,024,957 | -650,472,463 |
