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 250,652,545, 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 | 250,652,545 | |
| -1 | -250,652,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 250,652,545.
Example:
1 x 250,652,545 = 250,652,545
and
-1 x -250,652,545 = 250,652,545
Notice both answers equal 250,652,545
With that explanation out of the way, let's continue. Next, we take the number 250,652,545 and divide it by 2:
250,652,545 ÷ 2 = 125,326,272.5
If the quotient is a whole number, then 2 and 125,326,272.5 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 | 250,652,545 | |
| -1 | -250,652,545 |
Now, we try dividing 250,652,545 by 3:
250,652,545 ÷ 3 = 83,550,848.3333
If the quotient is a whole number, then 3 and 83,550,848.3333 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 | 250,652,545 | |
| -1 | -250,652,545 |
Let's try dividing by 4:
250,652,545 ÷ 4 = 62,663,136.25
If the quotient is a whole number, then 4 and 62,663,136.25 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 | 250,652,545 | |
| -1 | 250,652,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 350,563 | 1,752,815 | 3,856,193 | 4,557,319 | 19,280,965 | 22,786,595 | 50,130,509 | 250,652,545 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -350,563 | -1,752,815 | -3,856,193 | -4,557,319 | -19,280,965 | -22,786,595 | -50,130,509 | -250,652,545 |
