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 141,537,847, 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 | 141,537,847 | |
| -1 | -141,537,847 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,537,847.
Example:
1 x 141,537,847 = 141,537,847
and
-1 x -141,537,847 = 141,537,847
Notice both answers equal 141,537,847
With that explanation out of the way, let's continue. Next, we take the number 141,537,847 and divide it by 2:
141,537,847 ÷ 2 = 70,768,923.5
If the quotient is a whole number, then 2 and 70,768,923.5 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 | 141,537,847 | |
| -1 | -141,537,847 |
Now, we try dividing 141,537,847 by 3:
141,537,847 ÷ 3 = 47,179,282.3333
If the quotient is a whole number, then 3 and 47,179,282.3333 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 | 141,537,847 | |
| -1 | -141,537,847 |
Let's try dividing by 4:
141,537,847 ÷ 4 = 35,384,461.75
If the quotient is a whole number, then 4 and 35,384,461.75 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 | 141,537,847 | |
| -1 | 141,537,847 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 269 | 341 | 1,543 | 2,959 | 8,339 | 16,973 | 47,833 | 91,729 | 415,067 | 526,163 | 4,565,737 | 12,867,077 | 141,537,847 |
| -1 | -11 | -31 | -269 | -341 | -1,543 | -2,959 | -8,339 | -16,973 | -47,833 | -91,729 | -415,067 | -526,163 | -4,565,737 | -12,867,077 | -141,537,847 |
