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 10,242,557, 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 | 10,242,557 | |
| -1 | -10,242,557 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,242,557.
Example:
1 x 10,242,557 = 10,242,557
and
-1 x -10,242,557 = 10,242,557
Notice both answers equal 10,242,557
With that explanation out of the way, let's continue. Next, we take the number 10,242,557 and divide it by 2:
10,242,557 ÷ 2 = 5,121,278.5
If the quotient is a whole number, then 2 and 5,121,278.5 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 | 10,242,557 | |
| -1 | -10,242,557 |
Now, we try dividing 10,242,557 by 3:
10,242,557 ÷ 3 = 3,414,185.6667
If the quotient is a whole number, then 3 and 3,414,185.6667 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 | 10,242,557 | |
| -1 | -10,242,557 |
Let's try dividing by 4:
10,242,557 ÷ 4 = 2,560,639.25
If the quotient is a whole number, then 4 and 2,560,639.25 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 | 10,242,557 | |
| -1 | 10,242,557 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 73 | 251 | 559 | 949 | 3,139 | 3,263 | 10,793 | 18,323 | 40,807 | 140,309 | 238,199 | 787,889 | 10,242,557 |
| -1 | -13 | -43 | -73 | -251 | -559 | -949 | -3,139 | -3,263 | -10,793 | -18,323 | -40,807 | -140,309 | -238,199 | -787,889 | -10,242,557 |
