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 610,225, 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 | 610,225 | |
| -1 | -610,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 610,225.
Example:
1 x 610,225 = 610,225
and
-1 x -610,225 = 610,225
Notice both answers equal 610,225
With that explanation out of the way, let's continue. Next, we take the number 610,225 and divide it by 2:
610,225 ÷ 2 = 305,112.5
If the quotient is a whole number, then 2 and 305,112.5 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 | 610,225 | |
| -1 | -610,225 |
Now, we try dividing 610,225 by 3:
610,225 ÷ 3 = 203,408.3333
If the quotient is a whole number, then 3 and 203,408.3333 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 | 610,225 | |
| -1 | -610,225 |
Let's try dividing by 4:
610,225 ÷ 4 = 152,556.25
If the quotient is a whole number, then 4 and 152,556.25 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 | 610,225 | |
| -1 | 610,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 25 | 35 | 55 | 77 | 175 | 275 | 317 | 385 | 1,585 | 1,925 | 2,219 | 3,487 | 7,925 | 11,095 | 17,435 | 24,409 | 55,475 | 87,175 | 122,045 | 610,225 |
| -1 | -5 | -7 | -11 | -25 | -35 | -55 | -77 | -175 | -275 | -317 | -385 | -1,585 | -1,925 | -2,219 | -3,487 | -7,925 | -11,095 | -17,435 | -24,409 | -55,475 | -87,175 | -122,045 | -610,225 |
