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 13,543,525, 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 | 13,543,525 | |
| -1 | -13,543,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,543,525.
Example:
1 x 13,543,525 = 13,543,525
and
-1 x -13,543,525 = 13,543,525
Notice both answers equal 13,543,525
With that explanation out of the way, let's continue. Next, we take the number 13,543,525 and divide it by 2:
13,543,525 ÷ 2 = 6,771,762.5
If the quotient is a whole number, then 2 and 6,771,762.5 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 | 13,543,525 | |
| -1 | -13,543,525 |
Now, we try dividing 13,543,525 by 3:
13,543,525 ÷ 3 = 4,514,508.3333
If the quotient is a whole number, then 3 and 4,514,508.3333 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 | 13,543,525 | |
| -1 | -13,543,525 |
Let's try dividing by 4:
13,543,525 ÷ 4 = 3,385,881.25
If the quotient is a whole number, then 4 and 3,385,881.25 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 | 13,543,525 | |
| -1 | 13,543,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 61 | 83 | 107 | 305 | 415 | 535 | 1,525 | 2,075 | 2,675 | 5,063 | 6,527 | 8,881 | 25,315 | 32,635 | 44,405 | 126,575 | 163,175 | 222,025 | 541,741 | 2,708,705 | 13,543,525 |
| -1 | -5 | -25 | -61 | -83 | -107 | -305 | -415 | -535 | -1,525 | -2,075 | -2,675 | -5,063 | -6,527 | -8,881 | -25,315 | -32,635 | -44,405 | -126,575 | -163,175 | -222,025 | -541,741 | -2,708,705 | -13,543,525 |
