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 27,458,041, 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 | 27,458,041 | |
| -1 | -27,458,041 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,458,041.
Example:
1 x 27,458,041 = 27,458,041
and
-1 x -27,458,041 = 27,458,041
Notice both answers equal 27,458,041
With that explanation out of the way, let's continue. Next, we take the number 27,458,041 and divide it by 2:
27,458,041 ÷ 2 = 13,729,020.5
If the quotient is a whole number, then 2 and 13,729,020.5 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 | 27,458,041 | |
| -1 | -27,458,041 |
Now, we try dividing 27,458,041 by 3:
27,458,041 ÷ 3 = 9,152,680.3333
If the quotient is a whole number, then 3 and 9,152,680.3333 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 | 27,458,041 | |
| -1 | -27,458,041 |
Let's try dividing by 4:
27,458,041 ÷ 4 = 6,864,510.25
If the quotient is a whole number, then 4 and 6,864,510.25 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 | 27,458,041 | |
| -1 | 27,458,041 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 173 | 377 | 421 | 2,249 | 5,017 | 5,473 | 12,209 | 65,221 | 72,833 | 158,717 | 946,829 | 2,112,157 | 27,458,041 |
| -1 | -13 | -29 | -173 | -377 | -421 | -2,249 | -5,017 | -5,473 | -12,209 | -65,221 | -72,833 | -158,717 | -946,829 | -2,112,157 | -27,458,041 |
