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 1,415,351, 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 | 1,415,351 | |
| -1 | -1,415,351 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,415,351.
Example:
1 x 1,415,351 = 1,415,351
and
-1 x -1,415,351 = 1,415,351
Notice both answers equal 1,415,351
With that explanation out of the way, let's continue. Next, we take the number 1,415,351 and divide it by 2:
1,415,351 ÷ 2 = 707,675.5
If the quotient is a whole number, then 2 and 707,675.5 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 | 1,415,351 | |
| -1 | -1,415,351 |
Now, we try dividing 1,415,351 by 3:
1,415,351 ÷ 3 = 471,783.6667
If the quotient is a whole number, then 3 and 471,783.6667 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 | 1,415,351 | |
| -1 | -1,415,351 |
Let's try dividing by 4:
1,415,351 ÷ 4 = 353,837.75
If the quotient is a whole number, then 4 and 353,837.75 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 | 1,415,351 | |
| -1 | 1,415,351 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 59 | 149 | 161 | 413 | 1,043 | 1,357 | 3,427 | 8,791 | 9,499 | 23,989 | 61,537 | 202,193 | 1,415,351 |
| -1 | -7 | -23 | -59 | -149 | -161 | -413 | -1,043 | -1,357 | -3,427 | -8,791 | -9,499 | -23,989 | -61,537 | -202,193 | -1,415,351 |
