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 4,237,387, 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 | 4,237,387 | |
| -1 | -4,237,387 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,237,387.
Example:
1 x 4,237,387 = 4,237,387
and
-1 x -4,237,387 = 4,237,387
Notice both answers equal 4,237,387
With that explanation out of the way, let's continue. Next, we take the number 4,237,387 and divide it by 2:
4,237,387 ÷ 2 = 2,118,693.5
If the quotient is a whole number, then 2 and 2,118,693.5 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 | 4,237,387 | |
| -1 | -4,237,387 |
Now, we try dividing 4,237,387 by 3:
4,237,387 ÷ 3 = 1,412,462.3333
If the quotient is a whole number, then 3 and 1,412,462.3333 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 | 4,237,387 | |
| -1 | -4,237,387 |
Let's try dividing by 4:
4,237,387 ÷ 4 = 1,059,346.75
If the quotient is a whole number, then 4 and 1,059,346.75 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 | 4,237,387 | |
| -1 | 4,237,387 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 113 | 487 | 791 | 1,243 | 3,409 | 5,357 | 8,701 | 37,499 | 55,031 | 385,217 | 605,341 | 4,237,387 |
| -1 | -7 | -11 | -77 | -113 | -487 | -791 | -1,243 | -3,409 | -5,357 | -8,701 | -37,499 | -55,031 | -385,217 | -605,341 | -4,237,387 |
