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 250,644,667, 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 | 250,644,667 | |
| -1 | -250,644,667 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 250,644,667.
Example:
1 x 250,644,667 = 250,644,667
and
-1 x -250,644,667 = 250,644,667
Notice both answers equal 250,644,667
With that explanation out of the way, let's continue. Next, we take the number 250,644,667 and divide it by 2:
250,644,667 ÷ 2 = 125,322,333.5
If the quotient is a whole number, then 2 and 125,322,333.5 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 | 250,644,667 | |
| -1 | -250,644,667 |
Now, we try dividing 250,644,667 by 3:
250,644,667 ÷ 3 = 83,548,222.3333
If the quotient is a whole number, then 3 and 83,548,222.3333 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 | 250,644,667 | |
| -1 | -250,644,667 |
Let's try dividing by 4:
250,644,667 ÷ 4 = 62,661,166.75
If the quotient is a whole number, then 4 and 62,661,166.75 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 | 250,644,667 | |
| -1 | 250,644,667 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 853 | 3,229 | 5,971 | 11,089 | 22,603 | 41,977 | 77,623 | 293,839 | 2,754,337 | 19,280,359 | 35,806,381 | 250,644,667 |
| -1 | -7 | -13 | -91 | -853 | -3,229 | -5,971 | -11,089 | -22,603 | -41,977 | -77,623 | -293,839 | -2,754,337 | -19,280,359 | -35,806,381 | -250,644,667 |
