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 5,101,615, 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 | 5,101,615 | |
| -1 | -5,101,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,101,615.
Example:
1 x 5,101,615 = 5,101,615
and
-1 x -5,101,615 = 5,101,615
Notice both answers equal 5,101,615
With that explanation out of the way, let's continue. Next, we take the number 5,101,615 and divide it by 2:
5,101,615 ÷ 2 = 2,550,807.5
If the quotient is a whole number, then 2 and 2,550,807.5 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 | 5,101,615 | |
| -1 | -5,101,615 |
Now, we try dividing 5,101,615 by 3:
5,101,615 ÷ 3 = 1,700,538.3333
If the quotient is a whole number, then 3 and 1,700,538.3333 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 | 5,101,615 | |
| -1 | -5,101,615 |
Let's try dividing by 4:
5,101,615 ÷ 4 = 1,275,403.75
If the quotient is a whole number, then 4 and 1,275,403.75 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 | 5,101,615 | |
| -1 | 5,101,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 47 | 85 | 235 | 799 | 1,277 | 3,995 | 6,385 | 21,709 | 60,019 | 108,545 | 300,095 | 1,020,323 | 5,101,615 |
| -1 | -5 | -17 | -47 | -85 | -235 | -799 | -1,277 | -3,995 | -6,385 | -21,709 | -60,019 | -108,545 | -300,095 | -1,020,323 | -5,101,615 |
