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 3,117,763, 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 | 3,117,763 | |
| -1 | -3,117,763 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,117,763.
Example:
1 x 3,117,763 = 3,117,763
and
-1 x -3,117,763 = 3,117,763
Notice both answers equal 3,117,763
With that explanation out of the way, let's continue. Next, we take the number 3,117,763 and divide it by 2:
3,117,763 ÷ 2 = 1,558,881.5
If the quotient is a whole number, then 2 and 1,558,881.5 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 | 3,117,763 | |
| -1 | -3,117,763 |
Now, we try dividing 3,117,763 by 3:
3,117,763 ÷ 3 = 1,039,254.3333
If the quotient is a whole number, then 3 and 1,039,254.3333 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 | 3,117,763 | |
| -1 | -3,117,763 |
Let's try dividing by 4:
3,117,763 ÷ 4 = 779,440.75
If the quotient is a whole number, then 4 and 779,440.75 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 | 3,117,763 | |
| -1 | 3,117,763 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 41 | 223 | 341 | 451 | 1,271 | 2,453 | 6,913 | 9,143 | 13,981 | 76,043 | 100,573 | 283,433 | 3,117,763 |
| -1 | -11 | -31 | -41 | -223 | -341 | -451 | -1,271 | -2,453 | -6,913 | -9,143 | -13,981 | -76,043 | -100,573 | -283,433 | -3,117,763 |
