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 1,486,123, 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 | 1,486,123 | |
| -1 | -1,486,123 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,486,123.
Example:
1 x 1,486,123 = 1,486,123
and
-1 x -1,486,123 = 1,486,123
Notice both answers equal 1,486,123
With that explanation out of the way, let's continue. Next, we take the number 1,486,123 and divide it by 2:
1,486,123 ÷ 2 = 743,061.5
If the quotient is a whole number, then 2 and 743,061.5 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 | 1,486,123 | |
| -1 | -1,486,123 |
Now, we try dividing 1,486,123 by 3:
1,486,123 ÷ 3 = 495,374.3333
If the quotient is a whole number, then 3 and 495,374.3333 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 | 1,486,123 | |
| -1 | -1,486,123 |
Let's try dividing by 4:
1,486,123 ÷ 4 = 371,530.75
If the quotient is a whole number, then 4 and 371,530.75 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 | 1,486,123 | |
| -1 | 1,486,123 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 43 | 107 | 323 | 731 | 817 | 1,819 | 2,033 | 4,601 | 13,889 | 34,561 | 78,217 | 87,419 | 1,486,123 |
| -1 | -17 | -19 | -43 | -107 | -323 | -731 | -817 | -1,819 | -2,033 | -4,601 | -13,889 | -34,561 | -78,217 | -87,419 | -1,486,123 |
