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 3,716,225, 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 | 3,716,225 | |
| -1 | -3,716,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,716,225.
Example:
1 x 3,716,225 = 3,716,225
and
-1 x -3,716,225 = 3,716,225
Notice both answers equal 3,716,225
With that explanation out of the way, let's continue. Next, we take the number 3,716,225 and divide it by 2:
3,716,225 ÷ 2 = 1,858,112.5
If the quotient is a whole number, then 2 and 1,858,112.5 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 | 3,716,225 | |
| -1 | -3,716,225 |
Now, we try dividing 3,716,225 by 3:
3,716,225 ÷ 3 = 1,238,741.6667
If the quotient is a whole number, then 3 and 1,238,741.6667 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 | 3,716,225 | |
| -1 | -3,716,225 |
Let's try dividing by 4:
3,716,225 ÷ 4 = 929,056.25
If the quotient is a whole number, then 4 and 929,056.25 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 | 3,716,225 | |
| -1 | 3,716,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 115 | 281 | 529 | 575 | 1,405 | 2,645 | 6,463 | 7,025 | 13,225 | 32,315 | 148,649 | 161,575 | 743,245 | 3,716,225 |
| -1 | -5 | -23 | -25 | -115 | -281 | -529 | -575 | -1,405 | -2,645 | -6,463 | -7,025 | -13,225 | -32,315 | -148,649 | -161,575 | -743,245 | -3,716,225 |
