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 140,160,853, 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 | 140,160,853 | |
| -1 | -140,160,853 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 140,160,853.
Example:
1 x 140,160,853 = 140,160,853
and
-1 x -140,160,853 = 140,160,853
Notice both answers equal 140,160,853
With that explanation out of the way, let's continue. Next, we take the number 140,160,853 and divide it by 2:
140,160,853 ÷ 2 = 70,080,426.5
If the quotient is a whole number, then 2 and 70,080,426.5 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 | 140,160,853 | |
| -1 | -140,160,853 |
Now, we try dividing 140,160,853 by 3:
140,160,853 ÷ 3 = 46,720,284.3333
If the quotient is a whole number, then 3 and 46,720,284.3333 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 | 140,160,853 | |
| -1 | -140,160,853 |
Let's try dividing by 4:
140,160,853 ÷ 4 = 35,040,213.25
If the quotient is a whole number, then 4 and 35,040,213.25 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 | 140,160,853 | |
| -1 | 140,160,853 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 263 | 1,841 | 4,007 | 4,997 | 28,049 | 34,979 | 76,133 | 532,931 | 1,053,841 | 7,376,887 | 20,022,979 | 140,160,853 |
| -1 | -7 | -19 | -133 | -263 | -1,841 | -4,007 | -4,997 | -28,049 | -34,979 | -76,133 | -532,931 | -1,053,841 | -7,376,887 | -20,022,979 | -140,160,853 |
