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 5,601,421, 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 | 5,601,421 | |
| -1 | -5,601,421 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,601,421.
Example:
1 x 5,601,421 = 5,601,421
and
-1 x -5,601,421 = 5,601,421
Notice both answers equal 5,601,421
With that explanation out of the way, let's continue. Next, we take the number 5,601,421 and divide it by 2:
5,601,421 ÷ 2 = 2,800,710.5
If the quotient is a whole number, then 2 and 2,800,710.5 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 | 5,601,421 | |
| -1 | -5,601,421 |
Now, we try dividing 5,601,421 by 3:
5,601,421 ÷ 3 = 1,867,140.3333
If the quotient is a whole number, then 3 and 1,867,140.3333 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 | 5,601,421 | |
| -1 | -5,601,421 |
Let's try dividing by 4:
5,601,421 ÷ 4 = 1,400,355.25
If the quotient is a whole number, then 4 and 1,400,355.25 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 | 5,601,421 | |
| -1 | 5,601,421 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 83 | 217 | 311 | 581 | 2,177 | 2,573 | 9,641 | 18,011 | 25,813 | 67,487 | 180,691 | 800,203 | 5,601,421 |
| -1 | -7 | -31 | -83 | -217 | -311 | -581 | -2,177 | -2,573 | -9,641 | -18,011 | -25,813 | -67,487 | -180,691 | -800,203 | -5,601,421 |
