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 15,465,415, 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 | 15,465,415 | |
| -1 | -15,465,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,465,415.
Example:
1 x 15,465,415 = 15,465,415
and
-1 x -15,465,415 = 15,465,415
Notice both answers equal 15,465,415
With that explanation out of the way, let's continue. Next, we take the number 15,465,415 and divide it by 2:
15,465,415 ÷ 2 = 7,732,707.5
If the quotient is a whole number, then 2 and 7,732,707.5 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 | 15,465,415 | |
| -1 | -15,465,415 |
Now, we try dividing 15,465,415 by 3:
15,465,415 ÷ 3 = 5,155,138.3333
If the quotient is a whole number, then 3 and 5,155,138.3333 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 | 15,465,415 | |
| -1 | -15,465,415 |
Let's try dividing by 4:
15,465,415 ÷ 4 = 3,866,353.75
If the quotient is a whole number, then 4 and 3,866,353.75 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 | 15,465,415 | |
| -1 | 15,465,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 73 | 365 | 511 | 2,555 | 6,053 | 30,265 | 42,371 | 211,855 | 441,869 | 2,209,345 | 3,093,083 | 15,465,415 |
| -1 | -5 | -7 | -35 | -73 | -365 | -511 | -2,555 | -6,053 | -30,265 | -42,371 | -211,855 | -441,869 | -2,209,345 | -3,093,083 | -15,465,415 |
