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 1,478,015, 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 | 1,478,015 | |
| -1 | -1,478,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,478,015.
Example:
1 x 1,478,015 = 1,478,015
and
-1 x -1,478,015 = 1,478,015
Notice both answers equal 1,478,015
With that explanation out of the way, let's continue. Next, we take the number 1,478,015 and divide it by 2:
1,478,015 ÷ 2 = 739,007.5
If the quotient is a whole number, then 2 and 739,007.5 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 | 1,478,015 | |
| -1 | -1,478,015 |
Now, we try dividing 1,478,015 by 3:
1,478,015 ÷ 3 = 492,671.6667
If the quotient is a whole number, then 3 and 492,671.6667 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 | 1,478,015 | |
| -1 | -1,478,015 |
Let's try dividing by 4:
1,478,015 ÷ 4 = 369,503.75
If the quotient is a whole number, then 4 and 369,503.75 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 | 1,478,015 | |
| -1 | 1,478,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 121 | 349 | 385 | 605 | 847 | 1,745 | 2,443 | 3,839 | 4,235 | 12,215 | 19,195 | 26,873 | 42,229 | 134,365 | 211,145 | 295,603 | 1,478,015 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -121 | -349 | -385 | -605 | -847 | -1,745 | -2,443 | -3,839 | -4,235 | -12,215 | -19,195 | -26,873 | -42,229 | -134,365 | -211,145 | -295,603 | -1,478,015 |
