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 3,719,815, 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 | 3,719,815 | |
| -1 | -3,719,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,719,815.
Example:
1 x 3,719,815 = 3,719,815
and
-1 x -3,719,815 = 3,719,815
Notice both answers equal 3,719,815
With that explanation out of the way, let's continue. Next, we take the number 3,719,815 and divide it by 2:
3,719,815 ÷ 2 = 1,859,907.5
If the quotient is a whole number, then 2 and 1,859,907.5 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 | 3,719,815 | |
| -1 | -3,719,815 |
Now, we try dividing 3,719,815 by 3:
3,719,815 ÷ 3 = 1,239,938.3333
If the quotient is a whole number, then 3 and 1,239,938.3333 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 | 3,719,815 | |
| -1 | -3,719,815 |
Let's try dividing by 4:
3,719,815 ÷ 4 = 929,953.75
If the quotient is a whole number, then 4 and 929,953.75 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 | 3,719,815 | |
| -1 | 3,719,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 47 | 55 | 235 | 517 | 1,439 | 2,585 | 7,195 | 15,829 | 67,633 | 79,145 | 338,165 | 743,963 | 3,719,815 |
| -1 | -5 | -11 | -47 | -55 | -235 | -517 | -1,439 | -2,585 | -7,195 | -15,829 | -67,633 | -79,145 | -338,165 | -743,963 | -3,719,815 |
