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 134,343,365, 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 | 134,343,365 | |
| -1 | -134,343,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,343,365.
Example:
1 x 134,343,365 = 134,343,365
and
-1 x -134,343,365 = 134,343,365
Notice both answers equal 134,343,365
With that explanation out of the way, let's continue. Next, we take the number 134,343,365 and divide it by 2:
134,343,365 ÷ 2 = 67,171,682.5
If the quotient is a whole number, then 2 and 67,171,682.5 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 | 134,343,365 | |
| -1 | -134,343,365 |
Now, we try dividing 134,343,365 by 3:
134,343,365 ÷ 3 = 44,781,121.6667
If the quotient is a whole number, then 3 and 44,781,121.6667 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 | 134,343,365 | |
| -1 | -134,343,365 |
Let's try dividing by 4:
134,343,365 ÷ 4 = 33,585,841.25
If the quotient is a whole number, then 4 and 33,585,841.25 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 | 134,343,365 | |
| -1 | 134,343,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 337 | 1,685 | 4,381 | 6,133 | 21,905 | 30,665 | 79,729 | 398,645 | 2,066,821 | 10,334,105 | 26,868,673 | 134,343,365 |
| -1 | -5 | -13 | -65 | -337 | -1,685 | -4,381 | -6,133 | -21,905 | -30,665 | -79,729 | -398,645 | -2,066,821 | -10,334,105 | -26,868,673 | -134,343,365 |
