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 401,196, 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 | 401,196 | |
| -1 | -401,196 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 401,196.
Example:
1 x 401,196 = 401,196
and
-1 x -401,196 = 401,196
Notice both answers equal 401,196
With that explanation out of the way, let's continue. Next, we take the number 401,196 and divide it by 2:
401,196 ÷ 2 = 200,598
If the quotient is a whole number, then 2 and 200,598 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 200,598 | 401,196 | |
| -1 | -2 | -200,598 | -401,196 |
Now, we try dividing 401,196 by 3:
401,196 ÷ 3 = 133,732
If the quotient is a whole number, then 3 and 133,732 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 3 | 133,732 | 200,598 | 401,196 | |
| -1 | -2 | -3 | -133,732 | -200,598 | -401,196 |
Let's try dividing by 4:
401,196 ÷ 4 = 100,299
If the quotient is a whole number, then 4 and 100,299 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 3 | 4 | 100,299 | 133,732 | 200,598 | 401,196 | |
| -1 | -2 | -3 | -4 | -100,299 | -133,732 | -200,598 | 401,196 |
If you did it right, you will end up with this table:
| 1 | 2 | 3 | 4 | 6 | 12 | 67 | 134 | 201 | 268 | 402 | 499 | 804 | 998 | 1,497 | 1,996 | 2,994 | 5,988 | 33,433 | 66,866 | 100,299 | 133,732 | 200,598 | 401,196 |
| -1 | -2 | -3 | -4 | -6 | -12 | -67 | -134 | -201 | -268 | -402 | -499 | -804 | -998 | -1,497 | -1,996 | -2,994 | -5,988 | -33,433 | -66,866 | -100,299 | -133,732 | -200,598 | -401,196 |
