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 250,733,645, 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 | 250,733,645 | |
| -1 | -250,733,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 250,733,645.
Example:
1 x 250,733,645 = 250,733,645
and
-1 x -250,733,645 = 250,733,645
Notice both answers equal 250,733,645
With that explanation out of the way, let's continue. Next, we take the number 250,733,645 and divide it by 2:
250,733,645 ÷ 2 = 125,366,822.5
If the quotient is a whole number, then 2 and 125,366,822.5 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 | 250,733,645 | |
| -1 | -250,733,645 |
Now, we try dividing 250,733,645 by 3:
250,733,645 ÷ 3 = 83,577,881.6667
If the quotient is a whole number, then 3 and 83,577,881.6667 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 | 250,733,645 | |
| -1 | -250,733,645 |
Let's try dividing by 4:
250,733,645 ÷ 4 = 62,683,411.25
If the quotient is a whole number, then 4 and 62,683,411.25 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 | 250,733,645 | |
| -1 | 250,733,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 43 | 185 | 215 | 733 | 1,591 | 1,849 | 3,665 | 7,955 | 9,245 | 27,121 | 31,519 | 68,413 | 135,605 | 157,595 | 342,065 | 1,166,203 | 1,355,317 | 5,831,015 | 6,776,585 | 50,146,729 | 250,733,645 |
| -1 | -5 | -37 | -43 | -185 | -215 | -733 | -1,591 | -1,849 | -3,665 | -7,955 | -9,245 | -27,121 | -31,519 | -68,413 | -135,605 | -157,595 | -342,065 | -1,166,203 | -1,355,317 | -5,831,015 | -6,776,585 | -50,146,729 | -250,733,645 |
