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 250,200,275, 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 | 250,200,275 | |
| -1 | -250,200,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 250,200,275.
Example:
1 x 250,200,275 = 250,200,275
and
-1 x -250,200,275 = 250,200,275
Notice both answers equal 250,200,275
With that explanation out of the way, let's continue. Next, we take the number 250,200,275 and divide it by 2:
250,200,275 ÷ 2 = 125,100,137.5
If the quotient is a whole number, then 2 and 125,100,137.5 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 | 250,200,275 | |
| -1 | -250,200,275 |
Now, we try dividing 250,200,275 by 3:
250,200,275 ÷ 3 = 83,400,091.6667
If the quotient is a whole number, then 3 and 83,400,091.6667 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 | 250,200,275 | |
| -1 | -250,200,275 |
Let's try dividing by 4:
250,200,275 ÷ 4 = 62,550,068.75
If the quotient is a whole number, then 4 and 62,550,068.75 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 | 250,200,275 | |
| -1 | 250,200,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 169 | 325 | 845 | 4,225 | 59,219 | 296,095 | 769,847 | 1,480,475 | 3,849,235 | 10,008,011 | 19,246,175 | 50,040,055 | 250,200,275 |
| -1 | -5 | -13 | -25 | -65 | -169 | -325 | -845 | -4,225 | -59,219 | -296,095 | -769,847 | -1,480,475 | -3,849,235 | -10,008,011 | -19,246,175 | -50,040,055 | -250,200,275 |
