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 13,643,195, 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 | 13,643,195 | |
| -1 | -13,643,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,643,195.
Example:
1 x 13,643,195 = 13,643,195
and
-1 x -13,643,195 = 13,643,195
Notice both answers equal 13,643,195
With that explanation out of the way, let's continue. Next, we take the number 13,643,195 and divide it by 2:
13,643,195 ÷ 2 = 6,821,597.5
If the quotient is a whole number, then 2 and 6,821,597.5 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 | 13,643,195 | |
| -1 | -13,643,195 |
Now, we try dividing 13,643,195 by 3:
13,643,195 ÷ 3 = 4,547,731.6667
If the quotient is a whole number, then 3 and 4,547,731.6667 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 | 13,643,195 | |
| -1 | -13,643,195 |
Let's try dividing by 4:
13,643,195 ÷ 4 = 3,410,798.75
If the quotient is a whole number, then 4 and 3,410,798.75 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 | 13,643,195 | |
| -1 | 13,643,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 37 | 145 | 185 | 1,073 | 2,543 | 5,365 | 12,715 | 73,747 | 94,091 | 368,735 | 470,455 | 2,728,639 | 13,643,195 |
| -1 | -5 | -29 | -37 | -145 | -185 | -1,073 | -2,543 | -5,365 | -12,715 | -73,747 | -94,091 | -368,735 | -470,455 | -2,728,639 | -13,643,195 |
