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 141,168,685, 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 | 141,168,685 | |
| -1 | -141,168,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,168,685.
Example:
1 x 141,168,685 = 141,168,685
and
-1 x -141,168,685 = 141,168,685
Notice both answers equal 141,168,685
With that explanation out of the way, let's continue. Next, we take the number 141,168,685 and divide it by 2:
141,168,685 ÷ 2 = 70,584,342.5
If the quotient is a whole number, then 2 and 70,584,342.5 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 | 141,168,685 | |
| -1 | -141,168,685 |
Now, we try dividing 141,168,685 by 3:
141,168,685 ÷ 3 = 47,056,228.3333
If the quotient is a whole number, then 3 and 47,056,228.3333 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 | 141,168,685 | |
| -1 | -141,168,685 |
Let's try dividing by 4:
141,168,685 ÷ 4 = 35,292,171.25
If the quotient is a whole number, then 4 and 35,292,171.25 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 | 141,168,685 | |
| -1 | 141,168,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 89 | 445 | 623 | 3,115 | 45,319 | 226,595 | 317,233 | 1,586,165 | 4,033,391 | 20,166,955 | 28,233,737 | 141,168,685 |
| -1 | -5 | -7 | -35 | -89 | -445 | -623 | -3,115 | -45,319 | -226,595 | -317,233 | -1,586,165 | -4,033,391 | -20,166,955 | -28,233,737 | -141,168,685 |
