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 13,347,763, 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 | 13,347,763 | |
| -1 | -13,347,763 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,347,763.
Example:
1 x 13,347,763 = 13,347,763
and
-1 x -13,347,763 = 13,347,763
Notice both answers equal 13,347,763
With that explanation out of the way, let's continue. Next, we take the number 13,347,763 and divide it by 2:
13,347,763 ÷ 2 = 6,673,881.5
If the quotient is a whole number, then 2 and 6,673,881.5 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 | 13,347,763 | |
| -1 | -13,347,763 |
Now, we try dividing 13,347,763 by 3:
13,347,763 ÷ 3 = 4,449,254.3333
If the quotient is a whole number, then 3 and 4,449,254.3333 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 | 13,347,763 | |
| -1 | -13,347,763 |
Let's try dividing by 4:
13,347,763 ÷ 4 = 3,336,940.75
If the quotient is a whole number, then 4 and 3,336,940.75 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 | 13,347,763 | |
| -1 | 13,347,763 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 31 | 143 | 341 | 403 | 3,011 | 4,433 | 33,121 | 39,143 | 93,341 | 430,573 | 1,026,751 | 1,213,433 | 13,347,763 |
| -1 | -11 | -13 | -31 | -143 | -341 | -403 | -3,011 | -4,433 | -33,121 | -39,143 | -93,341 | -430,573 | -1,026,751 | -1,213,433 | -13,347,763 |
