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 134,416,163, 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 | 134,416,163 | |
| -1 | -134,416,163 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,416,163.
Example:
1 x 134,416,163 = 134,416,163
and
-1 x -134,416,163 = 134,416,163
Notice both answers equal 134,416,163
With that explanation out of the way, let's continue. Next, we take the number 134,416,163 and divide it by 2:
134,416,163 ÷ 2 = 67,208,081.5
If the quotient is a whole number, then 2 and 67,208,081.5 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 | 134,416,163 | |
| -1 | -134,416,163 |
Now, we try dividing 134,416,163 by 3:
134,416,163 ÷ 3 = 44,805,387.6667
If the quotient is a whole number, then 3 and 44,805,387.6667 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 | 134,416,163 | |
| -1 | -134,416,163 |
Let's try dividing by 4:
134,416,163 ÷ 4 = 33,604,040.75
If the quotient is a whole number, then 4 and 33,604,040.75 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 | 134,416,163 | |
| -1 | 134,416,163 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 41 | 49 | 161 | 287 | 943 | 1,127 | 2,009 | 2,909 | 6,601 | 20,363 | 46,207 | 66,907 | 119,269 | 142,541 | 468,349 | 834,883 | 2,743,187 | 3,278,443 | 5,844,181 | 19,202,309 | 134,416,163 |
| -1 | -7 | -23 | -41 | -49 | -161 | -287 | -943 | -1,127 | -2,009 | -2,909 | -6,601 | -20,363 | -46,207 | -66,907 | -119,269 | -142,541 | -468,349 | -834,883 | -2,743,187 | -3,278,443 | -5,844,181 | -19,202,309 | -134,416,163 |
