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 3,856,501, 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 | 3,856,501 | |
| -1 | -3,856,501 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,856,501.
Example:
1 x 3,856,501 = 3,856,501
and
-1 x -3,856,501 = 3,856,501
Notice both answers equal 3,856,501
With that explanation out of the way, let's continue. Next, we take the number 3,856,501 and divide it by 2:
3,856,501 ÷ 2 = 1,928,250.5
If the quotient is a whole number, then 2 and 1,928,250.5 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 | 3,856,501 | |
| -1 | -3,856,501 |
Now, we try dividing 3,856,501 by 3:
3,856,501 ÷ 3 = 1,285,500.3333
If the quotient is a whole number, then 3 and 1,285,500.3333 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 | 3,856,501 | |
| -1 | -3,856,501 |
Let's try dividing by 4:
3,856,501 ÷ 4 = 964,125.25
If the quotient is a whole number, then 4 and 964,125.25 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 | 3,856,501 | |
| -1 | 3,856,501 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 41 | 187 | 451 | 503 | 697 | 5,533 | 7,667 | 8,551 | 20,623 | 94,061 | 226,853 | 350,591 | 3,856,501 |
| -1 | -11 | -17 | -41 | -187 | -451 | -503 | -697 | -5,533 | -7,667 | -8,551 | -20,623 | -94,061 | -226,853 | -350,591 | -3,856,501 |
