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 14,961,065, 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 | 14,961,065 | |
| -1 | -14,961,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,961,065.
Example:
1 x 14,961,065 = 14,961,065
and
-1 x -14,961,065 = 14,961,065
Notice both answers equal 14,961,065
With that explanation out of the way, let's continue. Next, we take the number 14,961,065 and divide it by 2:
14,961,065 ÷ 2 = 7,480,532.5
If the quotient is a whole number, then 2 and 7,480,532.5 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 | 14,961,065 | |
| -1 | -14,961,065 |
Now, we try dividing 14,961,065 by 3:
14,961,065 ÷ 3 = 4,987,021.6667
If the quotient is a whole number, then 3 and 4,987,021.6667 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 | 14,961,065 | |
| -1 | -14,961,065 |
Let's try dividing by 4:
14,961,065 ÷ 4 = 3,740,266.25
If the quotient is a whole number, then 4 and 3,740,266.25 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 | 14,961,065 | |
| -1 | 14,961,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 155 | 217 | 1,085 | 13,789 | 68,945 | 96,523 | 427,459 | 482,615 | 2,137,295 | 2,992,213 | 14,961,065 |
| -1 | -5 | -7 | -31 | -35 | -155 | -217 | -1,085 | -13,789 | -68,945 | -96,523 | -427,459 | -482,615 | -2,137,295 | -2,992,213 | -14,961,065 |
