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 4,970,105, 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 | 4,970,105 | |
| -1 | -4,970,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,970,105.
Example:
1 x 4,970,105 = 4,970,105
and
-1 x -4,970,105 = 4,970,105
Notice both answers equal 4,970,105
With that explanation out of the way, let's continue. Next, we take the number 4,970,105 and divide it by 2:
4,970,105 ÷ 2 = 2,485,052.5
If the quotient is a whole number, then 2 and 2,485,052.5 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 | 4,970,105 | |
| -1 | -4,970,105 |
Now, we try dividing 4,970,105 by 3:
4,970,105 ÷ 3 = 1,656,701.6667
If the quotient is a whole number, then 3 and 1,656,701.6667 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 | 4,970,105 | |
| -1 | -4,970,105 |
Let's try dividing by 4:
4,970,105 ÷ 4 = 1,242,526.25
If the quotient is a whole number, then 4 and 1,242,526.25 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 | 4,970,105 | |
| -1 | 4,970,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 211 | 673 | 1,055 | 1,477 | 3,365 | 4,711 | 7,385 | 23,555 | 142,003 | 710,015 | 994,021 | 4,970,105 |
| -1 | -5 | -7 | -35 | -211 | -673 | -1,055 | -1,477 | -3,365 | -4,711 | -7,385 | -23,555 | -142,003 | -710,015 | -994,021 | -4,970,105 |
