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 4,581,175, 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 | 4,581,175 | |
-1 | -4,581,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,581,175.
Example:
1 x 4,581,175 = 4,581,175
and
-1 x -4,581,175 = 4,581,175
Notice both answers equal 4,581,175
With that explanation out of the way, let's continue. Next, we take the number 4,581,175 and divide it by 2:
4,581,175 ÷ 2 = 2,290,587.5
If the quotient is a whole number, then 2 and 2,290,587.5 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 | 4,581,175 | |
-1 | -4,581,175 |
Now, we try dividing 4,581,175 by 3:
4,581,175 ÷ 3 = 1,527,058.3333
If the quotient is a whole number, then 3 and 1,527,058.3333 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 | 4,581,175 | |
-1 | -4,581,175 |
Let's try dividing by 4:
4,581,175 ÷ 4 = 1,145,293.75
If the quotient is a whole number, then 4 and 1,145,293.75 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 | 4,581,175 | |
-1 | 4,581,175 |
If you did it right, you will end up with this table:
1 | 5 | 25 | 183,247 | 916,235 | 4,581,175 |
-1 | -5 | -25 | -183,247 | -916,235 | -4,581,175 |
