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 63,422,209, 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 | 63,422,209 | |
| -1 | -63,422,209 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 63,422,209.
Example:
1 x 63,422,209 = 63,422,209
and
-1 x -63,422,209 = 63,422,209
Notice both answers equal 63,422,209
With that explanation out of the way, let's continue. Next, we take the number 63,422,209 and divide it by 2:
63,422,209 ÷ 2 = 31,711,104.5
If the quotient is a whole number, then 2 and 31,711,104.5 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 | 63,422,209 | |
| -1 | -63,422,209 |
Now, we try dividing 63,422,209 by 3:
63,422,209 ÷ 3 = 21,140,736.3333
If the quotient is a whole number, then 3 and 21,140,736.3333 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 | 63,422,209 | |
| -1 | -63,422,209 |
Let's try dividing by 4:
63,422,209 ÷ 4 = 15,855,552.25
If the quotient is a whole number, then 4 and 15,855,552.25 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 | 63,422,209 | |
| -1 | 63,422,209 |
If you did it right, you will end up with this table:
| 1 | 19 | 83 | 131 | 307 | 1,577 | 2,489 | 5,833 | 10,873 | 25,481 | 40,217 | 206,587 | 484,139 | 764,123 | 3,338,011 | 63,422,209 |
| -1 | -19 | -83 | -131 | -307 | -1,577 | -2,489 | -5,833 | -10,873 | -25,481 | -40,217 | -206,587 | -484,139 | -764,123 | -3,338,011 | -63,422,209 |
