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 250,354,225, 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 | 250,354,225 | |
| -1 | -250,354,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 250,354,225.
Example:
1 x 250,354,225 = 250,354,225
and
-1 x -250,354,225 = 250,354,225
Notice both answers equal 250,354,225
With that explanation out of the way, let's continue. Next, we take the number 250,354,225 and divide it by 2:
250,354,225 ÷ 2 = 125,177,112.5
If the quotient is a whole number, then 2 and 125,177,112.5 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 | 250,354,225 | |
| -1 | -250,354,225 |
Now, we try dividing 250,354,225 by 3:
250,354,225 ÷ 3 = 83,451,408.3333
If the quotient is a whole number, then 3 and 83,451,408.3333 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 | 250,354,225 | |
| -1 | -250,354,225 |
Let's try dividing by 4:
250,354,225 ÷ 4 = 62,588,556.25
If the quotient is a whole number, then 4 and 62,588,556.25 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 | 250,354,225 | |
| -1 | 250,354,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 151 | 275 | 755 | 1,661 | 3,775 | 6,029 | 8,305 | 30,145 | 41,525 | 66,319 | 150,725 | 331,595 | 910,379 | 1,657,975 | 4,551,895 | 10,014,169 | 22,759,475 | 50,070,845 | 250,354,225 |
| -1 | -5 | -11 | -25 | -55 | -151 | -275 | -755 | -1,661 | -3,775 | -6,029 | -8,305 | -30,145 | -41,525 | -66,319 | -150,725 | -331,595 | -910,379 | -1,657,975 | -4,551,895 | -10,014,169 | -22,759,475 | -50,070,845 | -250,354,225 |
