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 4,731,965, 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 | 4,731,965 | |
| -1 | -4,731,965 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,731,965.
Example:
1 x 4,731,965 = 4,731,965
and
-1 x -4,731,965 = 4,731,965
Notice both answers equal 4,731,965
With that explanation out of the way, let's continue. Next, we take the number 4,731,965 and divide it by 2:
4,731,965 ÷ 2 = 2,365,982.5
If the quotient is a whole number, then 2 and 2,365,982.5 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 | 4,731,965 | |
| -1 | -4,731,965 |
Now, we try dividing 4,731,965 by 3:
4,731,965 ÷ 3 = 1,577,321.6667
If the quotient is a whole number, then 3 and 1,577,321.6667 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 | 4,731,965 | |
| -1 | -4,731,965 |
Let's try dividing by 4:
4,731,965 ÷ 4 = 1,182,991.25
If the quotient is a whole number, then 4 and 1,182,991.25 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 | 4,731,965 | |
| -1 | 4,731,965 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 353 | 383 | 1,765 | 1,915 | 2,471 | 2,681 | 12,355 | 13,405 | 135,199 | 675,995 | 946,393 | 4,731,965 |
| -1 | -5 | -7 | -35 | -353 | -383 | -1,765 | -1,915 | -2,471 | -2,681 | -12,355 | -13,405 | -135,199 | -675,995 | -946,393 | -4,731,965 |
