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 4,640,185, 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 | 4,640,185 | |
| -1 | -4,640,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,640,185.
Example:
1 x 4,640,185 = 4,640,185
and
-1 x -4,640,185 = 4,640,185
Notice both answers equal 4,640,185
With that explanation out of the way, let's continue. Next, we take the number 4,640,185 and divide it by 2:
4,640,185 ÷ 2 = 2,320,092.5
If the quotient is a whole number, then 2 and 2,320,092.5 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 | 4,640,185 | |
| -1 | -4,640,185 |
Now, we try dividing 4,640,185 by 3:
4,640,185 ÷ 3 = 1,546,728.3333
If the quotient is a whole number, then 3 and 1,546,728.3333 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 | 4,640,185 | |
| -1 | -4,640,185 |
Let's try dividing by 4:
4,640,185 ÷ 4 = 1,160,046.25
If the quotient is a whole number, then 4 and 1,160,046.25 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 | 4,640,185 | |
| -1 | 4,640,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 239 | 353 | 1,195 | 1,765 | 2,629 | 3,883 | 13,145 | 19,415 | 84,367 | 421,835 | 928,037 | 4,640,185 |
| -1 | -5 | -11 | -55 | -239 | -353 | -1,195 | -1,765 | -2,629 | -3,883 | -13,145 | -19,415 | -84,367 | -421,835 | -928,037 | -4,640,185 |
