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 250,636,249, 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 | 250,636,249 | |
-1 | -250,636,249 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 250,636,249.
Example:
1 x 250,636,249 = 250,636,249
and
-1 x -250,636,249 = 250,636,249
Notice both answers equal 250,636,249
With that explanation out of the way, let's continue. Next, we take the number 250,636,249 and divide it by 2:
250,636,249 ÷ 2 = 125,318,124.5
If the quotient is a whole number, then 2 and 125,318,124.5 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 | 250,636,249 | |
-1 | -250,636,249 |
Now, we try dividing 250,636,249 by 3:
250,636,249 ÷ 3 = 83,545,416.3333
If the quotient is a whole number, then 3 and 83,545,416.3333 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 | 250,636,249 | |
-1 | -250,636,249 |
Let's try dividing by 4:
250,636,249 ÷ 4 = 62,659,062.25
If the quotient is a whole number, then 4 and 62,659,062.25 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 | 250,636,249 | |
-1 | 250,636,249 |
If you did it right, you will end up with this table:
1 | 1,579 | 158,731 | 250,636,249 |
-1 | -1,579 | -158,731 | -250,636,249 |
