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 10,873,219, 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 | 10,873,219 | |
| -1 | -10,873,219 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,873,219.
Example:
1 x 10,873,219 = 10,873,219
and
-1 x -10,873,219 = 10,873,219
Notice both answers equal 10,873,219
With that explanation out of the way, let's continue. Next, we take the number 10,873,219 and divide it by 2:
10,873,219 ÷ 2 = 5,436,609.5
If the quotient is a whole number, then 2 and 5,436,609.5 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 | 10,873,219 | |
| -1 | -10,873,219 |
Now, we try dividing 10,873,219 by 3:
10,873,219 ÷ 3 = 3,624,406.3333
If the quotient is a whole number, then 3 and 3,624,406.3333 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 | 10,873,219 | |
| -1 | -10,873,219 |
Let's try dividing by 4:
10,873,219 ÷ 4 = 2,718,304.75
If the quotient is a whole number, then 4 and 2,718,304.75 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 | 10,873,219 | |
| -1 | 10,873,219 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 89 | 217 | 563 | 623 | 2,759 | 3,941 | 17,453 | 19,313 | 50,107 | 122,171 | 350,749 | 1,553,317 | 10,873,219 |
| -1 | -7 | -31 | -89 | -217 | -563 | -623 | -2,759 | -3,941 | -17,453 | -19,313 | -50,107 | -122,171 | -350,749 | -1,553,317 | -10,873,219 |
