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 250,151,345, 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 | 250,151,345 | |
| -1 | -250,151,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 250,151,345.
Example:
1 x 250,151,345 = 250,151,345
and
-1 x -250,151,345 = 250,151,345
Notice both answers equal 250,151,345
With that explanation out of the way, let's continue. Next, we take the number 250,151,345 and divide it by 2:
250,151,345 ÷ 2 = 125,075,672.5
If the quotient is a whole number, then 2 and 125,075,672.5 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 | 250,151,345 | |
| -1 | -250,151,345 |
Now, we try dividing 250,151,345 by 3:
250,151,345 ÷ 3 = 83,383,781.6667
If the quotient is a whole number, then 3 and 83,383,781.6667 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 | 250,151,345 | |
| -1 | -250,151,345 |
Let's try dividing by 4:
250,151,345 ÷ 4 = 62,537,836.25
If the quotient is a whole number, then 4 and 62,537,836.25 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 | 250,151,345 | |
| -1 | 250,151,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 1,069 | 2,753 | 5,345 | 13,765 | 18,173 | 46,801 | 90,865 | 234,005 | 2,942,957 | 14,714,785 | 50,030,269 | 250,151,345 |
| -1 | -5 | -17 | -85 | -1,069 | -2,753 | -5,345 | -13,765 | -18,173 | -46,801 | -90,865 | -234,005 | -2,942,957 | -14,714,785 | -50,030,269 | -250,151,345 |
