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 4,243,213, 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 | 4,243,213 | |
| -1 | -4,243,213 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,243,213.
Example:
1 x 4,243,213 = 4,243,213
and
-1 x -4,243,213 = 4,243,213
Notice both answers equal 4,243,213
With that explanation out of the way, let's continue. Next, we take the number 4,243,213 and divide it by 2:
4,243,213 ÷ 2 = 2,121,606.5
If the quotient is a whole number, then 2 and 2,121,606.5 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 | 4,243,213 | |
| -1 | -4,243,213 |
Now, we try dividing 4,243,213 by 3:
4,243,213 ÷ 3 = 1,414,404.3333
If the quotient is a whole number, then 3 and 1,414,404.3333 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 | 4,243,213 | |
| -1 | -4,243,213 |
Let's try dividing by 4:
4,243,213 ÷ 4 = 1,060,803.25
If the quotient is a whole number, then 4 and 1,060,803.25 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 | 4,243,213 | |
| -1 | 4,243,213 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 41 | 247 | 419 | 533 | 779 | 5,447 | 7,961 | 10,127 | 17,179 | 103,493 | 223,327 | 326,401 | 4,243,213 |
| -1 | -13 | -19 | -41 | -247 | -419 | -533 | -779 | -5,447 | -7,961 | -10,127 | -17,179 | -103,493 | -223,327 | -326,401 | -4,243,213 |
