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 250,340,533, 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 | 250,340,533 | |
| -1 | -250,340,533 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 250,340,533.
Example:
1 x 250,340,533 = 250,340,533
and
-1 x -250,340,533 = 250,340,533
Notice both answers equal 250,340,533
With that explanation out of the way, let's continue. Next, we take the number 250,340,533 and divide it by 2:
250,340,533 ÷ 2 = 125,170,266.5
If the quotient is a whole number, then 2 and 125,170,266.5 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 | 250,340,533 | |
| -1 | -250,340,533 |
Now, we try dividing 250,340,533 by 3:
250,340,533 ÷ 3 = 83,446,844.3333
If the quotient is a whole number, then 3 and 83,446,844.3333 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 | 250,340,533 | |
| -1 | -250,340,533 |
Let's try dividing by 4:
250,340,533 ÷ 4 = 62,585,133.25
If the quotient is a whole number, then 4 and 62,585,133.25 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 | 250,340,533 | |
| -1 | 250,340,533 |
If you did it right, you will end up with this table:
| 1 | 23 | 71 | 83 | 1,633 | 1,847 | 1,909 | 5,893 | 42,481 | 131,137 | 135,539 | 153,301 | 3,016,151 | 3,525,923 | 10,884,371 | 250,340,533 |
| -1 | -23 | -71 | -83 | -1,633 | -1,847 | -1,909 | -5,893 | -42,481 | -131,137 | -135,539 | -153,301 | -3,016,151 | -3,525,923 | -10,884,371 | -250,340,533 |
