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 5,221,051, 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 | 5,221,051 | |
| -1 | -5,221,051 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,221,051.
Example:
1 x 5,221,051 = 5,221,051
and
-1 x -5,221,051 = 5,221,051
Notice both answers equal 5,221,051
With that explanation out of the way, let's continue. Next, we take the number 5,221,051 and divide it by 2:
5,221,051 ÷ 2 = 2,610,525.5
If the quotient is a whole number, then 2 and 2,610,525.5 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 | 5,221,051 | |
| -1 | -5,221,051 |
Now, we try dividing 5,221,051 by 3:
5,221,051 ÷ 3 = 1,740,350.3333
If the quotient is a whole number, then 3 and 1,740,350.3333 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 | 5,221,051 | |
| -1 | -5,221,051 |
Let's try dividing by 4:
5,221,051 ÷ 4 = 1,305,262.75
If the quotient is a whole number, then 4 and 1,305,262.75 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 | 5,221,051 | |
| -1 | 5,221,051 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 61 | 251 | 341 | 671 | 1,891 | 2,761 | 7,781 | 15,311 | 20,801 | 85,591 | 168,421 | 474,641 | 5,221,051 |
| -1 | -11 | -31 | -61 | -251 | -341 | -671 | -1,891 | -2,761 | -7,781 | -15,311 | -20,801 | -85,591 | -168,421 | -474,641 | -5,221,051 |
