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 4,505,185, 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 | 4,505,185 | |
| -1 | -4,505,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,505,185.
Example:
1 x 4,505,185 = 4,505,185
and
-1 x -4,505,185 = 4,505,185
Notice both answers equal 4,505,185
With that explanation out of the way, let's continue. Next, we take the number 4,505,185 and divide it by 2:
4,505,185 ÷ 2 = 2,252,592.5
If the quotient is a whole number, then 2 and 2,252,592.5 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 | 4,505,185 | |
| -1 | -4,505,185 |
Now, we try dividing 4,505,185 by 3:
4,505,185 ÷ 3 = 1,501,728.3333
If the quotient is a whole number, then 3 and 1,501,728.3333 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 | 4,505,185 | |
| -1 | -4,505,185 |
Let's try dividing by 4:
4,505,185 ÷ 4 = 1,126,296.25
If the quotient is a whole number, then 4 and 1,126,296.25 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 | 4,505,185 | |
| -1 | 4,505,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 47 | 95 | 235 | 893 | 1,009 | 4,465 | 5,045 | 19,171 | 47,423 | 95,855 | 237,115 | 901,037 | 4,505,185 |
| -1 | -5 | -19 | -47 | -95 | -235 | -893 | -1,009 | -4,465 | -5,045 | -19,171 | -47,423 | -95,855 | -237,115 | -901,037 | -4,505,185 |
