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 13,763,197, 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 | 13,763,197 | |
| -1 | -13,763,197 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,763,197.
Example:
1 x 13,763,197 = 13,763,197
and
-1 x -13,763,197 = 13,763,197
Notice both answers equal 13,763,197
With that explanation out of the way, let's continue. Next, we take the number 13,763,197 and divide it by 2:
13,763,197 ÷ 2 = 6,881,598.5
If the quotient is a whole number, then 2 and 6,881,598.5 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 | 13,763,197 | |
| -1 | -13,763,197 |
Now, we try dividing 13,763,197 by 3:
13,763,197 ÷ 3 = 4,587,732.3333
If the quotient is a whole number, then 3 and 4,587,732.3333 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 | 13,763,197 | |
| -1 | -13,763,197 |
Let's try dividing by 4:
13,763,197 ÷ 4 = 3,440,799.25
If the quotient is a whole number, then 4 and 3,440,799.25 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 | 13,763,197 | |
| -1 | 13,763,197 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 151 | 203 | 449 | 1,057 | 3,143 | 4,379 | 13,021 | 30,653 | 67,799 | 91,147 | 474,593 | 1,966,171 | 13,763,197 |
| -1 | -7 | -29 | -151 | -203 | -449 | -1,057 | -3,143 | -4,379 | -13,021 | -30,653 | -67,799 | -91,147 | -474,593 | -1,966,171 | -13,763,197 |
