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 141,194,065, 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 | 141,194,065 | |
| -1 | -141,194,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,194,065.
Example:
1 x 141,194,065 = 141,194,065
and
-1 x -141,194,065 = 141,194,065
Notice both answers equal 141,194,065
With that explanation out of the way, let's continue. Next, we take the number 141,194,065 and divide it by 2:
141,194,065 ÷ 2 = 70,597,032.5
If the quotient is a whole number, then 2 and 70,597,032.5 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 | 141,194,065 | |
| -1 | -141,194,065 |
Now, we try dividing 141,194,065 by 3:
141,194,065 ÷ 3 = 47,064,688.3333
If the quotient is a whole number, then 3 and 47,064,688.3333 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 | 141,194,065 | |
| -1 | -141,194,065 |
Let's try dividing by 4:
141,194,065 ÷ 4 = 35,298,516.25
If the quotient is a whole number, then 4 and 35,298,516.25 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 | 141,194,065 | |
| -1 | 141,194,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 113 | 269 | 565 | 929 | 1,345 | 4,645 | 30,397 | 104,977 | 151,985 | 249,901 | 524,885 | 1,249,505 | 28,238,813 | 141,194,065 |
| -1 | -5 | -113 | -269 | -565 | -929 | -1,345 | -4,645 | -30,397 | -104,977 | -151,985 | -249,901 | -524,885 | -1,249,505 | -28,238,813 | -141,194,065 |
