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 3,722,225, 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 | 3,722,225 | |
| -1 | -3,722,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,722,225.
Example:
1 x 3,722,225 = 3,722,225
and
-1 x -3,722,225 = 3,722,225
Notice both answers equal 3,722,225
With that explanation out of the way, let's continue. Next, we take the number 3,722,225 and divide it by 2:
3,722,225 ÷ 2 = 1,861,112.5
If the quotient is a whole number, then 2 and 1,861,112.5 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 | 3,722,225 | |
| -1 | -3,722,225 |
Now, we try dividing 3,722,225 by 3:
3,722,225 ÷ 3 = 1,240,741.6667
If the quotient is a whole number, then 3 and 1,240,741.6667 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 | 3,722,225 | |
| -1 | -3,722,225 |
Let's try dividing by 4:
3,722,225 ÷ 4 = 930,556.25
If the quotient is a whole number, then 4 and 930,556.25 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 | 3,722,225 | |
| -1 | 3,722,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 169 | 325 | 845 | 881 | 4,225 | 4,405 | 11,453 | 22,025 | 57,265 | 148,889 | 286,325 | 744,445 | 3,722,225 |
| -1 | -5 | -13 | -25 | -65 | -169 | -325 | -845 | -881 | -4,225 | -4,405 | -11,453 | -22,025 | -57,265 | -148,889 | -286,325 | -744,445 | -3,722,225 |
