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 134,874,047, 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 | 134,874,047 | |
| -1 | -134,874,047 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,874,047.
Example:
1 x 134,874,047 = 134,874,047
and
-1 x -134,874,047 = 134,874,047
Notice both answers equal 134,874,047
With that explanation out of the way, let's continue. Next, we take the number 134,874,047 and divide it by 2:
134,874,047 ÷ 2 = 67,437,023.5
If the quotient is a whole number, then 2 and 67,437,023.5 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 | 134,874,047 | |
| -1 | -134,874,047 |
Now, we try dividing 134,874,047 by 3:
134,874,047 ÷ 3 = 44,958,015.6667
If the quotient is a whole number, then 3 and 44,958,015.6667 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 | 134,874,047 | |
| -1 | -134,874,047 |
Let's try dividing by 4:
134,874,047 ÷ 4 = 33,718,511.75
If the quotient is a whole number, then 4 and 33,718,511.75 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 | 134,874,047 | |
| -1 | 134,874,047 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 23 | 77 | 161 | 253 | 1,771 | 76,157 | 533,099 | 837,727 | 1,751,611 | 5,864,089 | 12,261,277 | 19,267,721 | 134,874,047 |
| -1 | -7 | -11 | -23 | -77 | -161 | -253 | -1,771 | -76,157 | -533,099 | -837,727 | -1,751,611 | -5,864,089 | -12,261,277 | -19,267,721 | -134,874,047 |
