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 3,787,063, 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 | 3,787,063 | |
| -1 | -3,787,063 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,787,063.
Example:
1 x 3,787,063 = 3,787,063
and
-1 x -3,787,063 = 3,787,063
Notice both answers equal 3,787,063
With that explanation out of the way, let's continue. Next, we take the number 3,787,063 and divide it by 2:
3,787,063 ÷ 2 = 1,893,531.5
If the quotient is a whole number, then 2 and 1,893,531.5 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 | 3,787,063 | |
| -1 | -3,787,063 |
Now, we try dividing 3,787,063 by 3:
3,787,063 ÷ 3 = 1,262,354.3333
If the quotient is a whole number, then 3 and 1,262,354.3333 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 | 3,787,063 | |
| -1 | -3,787,063 |
Let's try dividing by 4:
3,787,063 ÷ 4 = 946,765.75
If the quotient is a whole number, then 4 and 946,765.75 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 | 3,787,063 | |
| -1 | 3,787,063 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 61 | 181 | 343 | 427 | 1,267 | 2,989 | 8,869 | 11,041 | 20,923 | 62,083 | 77,287 | 541,009 | 3,787,063 |
| -1 | -7 | -49 | -61 | -181 | -343 | -427 | -1,267 | -2,989 | -8,869 | -11,041 | -20,923 | -62,083 | -77,287 | -541,009 | -3,787,063 |
