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 15,265,369, 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 | 15,265,369 | |
| -1 | -15,265,369 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,265,369.
Example:
1 x 15,265,369 = 15,265,369
and
-1 x -15,265,369 = 15,265,369
Notice both answers equal 15,265,369
With that explanation out of the way, let's continue. Next, we take the number 15,265,369 and divide it by 2:
15,265,369 ÷ 2 = 7,632,684.5
If the quotient is a whole number, then 2 and 7,632,684.5 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 | 15,265,369 | |
| -1 | -15,265,369 |
Now, we try dividing 15,265,369 by 3:
15,265,369 ÷ 3 = 5,088,456.3333
If the quotient is a whole number, then 3 and 5,088,456.3333 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 | 15,265,369 | |
| -1 | -15,265,369 |
Let's try dividing by 4:
15,265,369 ÷ 4 = 3,816,342.25
If the quotient is a whole number, then 4 and 3,816,342.25 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 | 15,265,369 | |
| -1 | 15,265,369 |
If you did it right, you will end up with this table:
| 1 | 7 | 89 | 107 | 229 | 623 | 749 | 1,603 | 9,523 | 20,381 | 24,503 | 66,661 | 142,667 | 171,521 | 2,180,767 | 15,265,369 |
| -1 | -7 | -89 | -107 | -229 | -623 | -749 | -1,603 | -9,523 | -20,381 | -24,503 | -66,661 | -142,667 | -171,521 | -2,180,767 | -15,265,369 |
