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 475,627,649, 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 | 475,627,649 | |
| -1 | -475,627,649 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 475,627,649.
Example:
1 x 475,627,649 = 475,627,649
and
-1 x -475,627,649 = 475,627,649
Notice both answers equal 475,627,649
With that explanation out of the way, let's continue. Next, we take the number 475,627,649 and divide it by 2:
475,627,649 ÷ 2 = 237,813,824.5
If the quotient is a whole number, then 2 and 237,813,824.5 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 | 475,627,649 | |
| -1 | -475,627,649 |
Now, we try dividing 475,627,649 by 3:
475,627,649 ÷ 3 = 158,542,549.6667
If the quotient is a whole number, then 3 and 158,542,549.6667 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 | 475,627,649 | |
| -1 | -475,627,649 |
Let's try dividing by 4:
475,627,649 ÷ 4 = 118,906,912.25
If the quotient is a whole number, then 4 and 118,906,912.25 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 | 475,627,649 | |
| -1 | 475,627,649 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 23 | 119 | 161 | 391 | 2,737 | 173,777 | 1,216,439 | 2,954,209 | 3,996,871 | 20,679,463 | 27,978,097 | 67,946,807 | 475,627,649 |
| -1 | -7 | -17 | -23 | -119 | -161 | -391 | -2,737 | -173,777 | -1,216,439 | -2,954,209 | -3,996,871 | -20,679,463 | -27,978,097 | -67,946,807 | -475,627,649 |
