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 107,528,281, 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 | 107,528,281 | |
| -1 | -107,528,281 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 107,528,281.
Example:
1 x 107,528,281 = 107,528,281
and
-1 x -107,528,281 = 107,528,281
Notice both answers equal 107,528,281
With that explanation out of the way, let's continue. Next, we take the number 107,528,281 and divide it by 2:
107,528,281 ÷ 2 = 53,764,140.5
If the quotient is a whole number, then 2 and 53,764,140.5 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 | 107,528,281 | |
| -1 | -107,528,281 |
Now, we try dividing 107,528,281 by 3:
107,528,281 ÷ 3 = 35,842,760.3333
If the quotient is a whole number, then 3 and 35,842,760.3333 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 | 107,528,281 | |
| -1 | -107,528,281 |
Let's try dividing by 4:
107,528,281 ÷ 4 = 26,882,070.25
If the quotient is a whole number, then 4 and 26,882,070.25 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 | 107,528,281 | |
| -1 | 107,528,281 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 41 | 119 | 287 | 697 | 4,879 | 22,039 | 154,273 | 374,663 | 903,599 | 2,622,641 | 6,325,193 | 15,361,183 | 107,528,281 |
| -1 | -7 | -17 | -41 | -119 | -287 | -697 | -4,879 | -22,039 | -154,273 | -374,663 | -903,599 | -2,622,641 | -6,325,193 | -15,361,183 | -107,528,281 |
