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 4,372,247, 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 | 4,372,247 | |
| -1 | -4,372,247 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,372,247.
Example:
1 x 4,372,247 = 4,372,247
and
-1 x -4,372,247 = 4,372,247
Notice both answers equal 4,372,247
With that explanation out of the way, let's continue. Next, we take the number 4,372,247 and divide it by 2:
4,372,247 ÷ 2 = 2,186,123.5
If the quotient is a whole number, then 2 and 2,186,123.5 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 | 4,372,247 | |
| -1 | -4,372,247 |
Now, we try dividing 4,372,247 by 3:
4,372,247 ÷ 3 = 1,457,415.6667
If the quotient is a whole number, then 3 and 1,457,415.6667 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 | 4,372,247 | |
| -1 | -4,372,247 |
Let's try dividing by 4:
4,372,247 ÷ 4 = 1,093,061.75
If the quotient is a whole number, then 4 and 1,093,061.75 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 | 4,372,247 | |
| -1 | 4,372,247 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 103 | 187 | 227 | 1,133 | 1,751 | 2,497 | 3,859 | 19,261 | 23,381 | 42,449 | 257,191 | 397,477 | 4,372,247 |
| -1 | -11 | -17 | -103 | -187 | -227 | -1,133 | -1,751 | -2,497 | -3,859 | -19,261 | -23,381 | -42,449 | -257,191 | -397,477 | -4,372,247 |
