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 3,849,517, 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 | 3,849,517 | |
| -1 | -3,849,517 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,849,517.
Example:
1 x 3,849,517 = 3,849,517
and
-1 x -3,849,517 = 3,849,517
Notice both answers equal 3,849,517
With that explanation out of the way, let's continue. Next, we take the number 3,849,517 and divide it by 2:
3,849,517 ÷ 2 = 1,924,758.5
If the quotient is a whole number, then 2 and 1,924,758.5 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 | 3,849,517 | |
| -1 | -3,849,517 |
Now, we try dividing 3,849,517 by 3:
3,849,517 ÷ 3 = 1,283,172.3333
If the quotient is a whole number, then 3 and 1,283,172.3333 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 | 3,849,517 | |
| -1 | -3,849,517 |
Let's try dividing by 4:
3,849,517 ÷ 4 = 962,379.25
If the quotient is a whole number, then 4 and 962,379.25 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 | 3,849,517 | |
| -1 | 3,849,517 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 89 | 167 | 259 | 623 | 1,169 | 3,293 | 6,179 | 14,863 | 23,051 | 43,253 | 104,041 | 549,931 | 3,849,517 |
| -1 | -7 | -37 | -89 | -167 | -259 | -623 | -1,169 | -3,293 | -6,179 | -14,863 | -23,051 | -43,253 | -104,041 | -549,931 | -3,849,517 |
