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 15,071,525, 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 | 15,071,525 | |
| -1 | -15,071,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,071,525.
Example:
1 x 15,071,525 = 15,071,525
and
-1 x -15,071,525 = 15,071,525
Notice both answers equal 15,071,525
With that explanation out of the way, let's continue. Next, we take the number 15,071,525 and divide it by 2:
15,071,525 ÷ 2 = 7,535,762.5
If the quotient is a whole number, then 2 and 7,535,762.5 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 | 15,071,525 | |
| -1 | -15,071,525 |
Now, we try dividing 15,071,525 by 3:
15,071,525 ÷ 3 = 5,023,841.6667
If the quotient is a whole number, then 3 and 5,023,841.6667 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 | 15,071,525 | |
| -1 | -15,071,525 |
Let's try dividing by 4:
15,071,525 ÷ 4 = 3,767,881.25
If the quotient is a whole number, then 4 and 3,767,881.25 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 | 15,071,525 | |
| -1 | 15,071,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 71 | 175 | 355 | 497 | 1,213 | 1,775 | 2,485 | 6,065 | 8,491 | 12,425 | 30,325 | 42,455 | 86,123 | 212,275 | 430,615 | 602,861 | 2,153,075 | 3,014,305 | 15,071,525 |
| -1 | -5 | -7 | -25 | -35 | -71 | -175 | -355 | -497 | -1,213 | -1,775 | -2,485 | -6,065 | -8,491 | -12,425 | -30,325 | -42,455 | -86,123 | -212,275 | -430,615 | -602,861 | -2,153,075 | -3,014,305 | -15,071,525 |
