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 15,350,435, 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 | 15,350,435 | |
| -1 | -15,350,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,350,435.
Example:
1 x 15,350,435 = 15,350,435
and
-1 x -15,350,435 = 15,350,435
Notice both answers equal 15,350,435
With that explanation out of the way, let's continue. Next, we take the number 15,350,435 and divide it by 2:
15,350,435 ÷ 2 = 7,675,217.5
If the quotient is a whole number, then 2 and 7,675,217.5 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 | 15,350,435 | |
| -1 | -15,350,435 |
Now, we try dividing 15,350,435 by 3:
15,350,435 ÷ 3 = 5,116,811.6667
If the quotient is a whole number, then 3 and 5,116,811.6667 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 | 15,350,435 | |
| -1 | -15,350,435 |
Let's try dividing by 4:
15,350,435 ÷ 4 = 3,837,608.75
If the quotient is a whole number, then 4 and 3,837,608.75 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 | 15,350,435 | |
| -1 | 15,350,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 83 | 235 | 415 | 787 | 3,901 | 3,935 | 19,505 | 36,989 | 65,321 | 184,945 | 326,605 | 3,070,087 | 15,350,435 |
| -1 | -5 | -47 | -83 | -235 | -415 | -787 | -3,901 | -3,935 | -19,505 | -36,989 | -65,321 | -184,945 | -326,605 | -3,070,087 | -15,350,435 |
