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 101,543,057, 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 | 101,543,057 | |
| -1 | -101,543,057 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 101,543,057.
Example:
1 x 101,543,057 = 101,543,057
and
-1 x -101,543,057 = 101,543,057
Notice both answers equal 101,543,057
With that explanation out of the way, let's continue. Next, we take the number 101,543,057 and divide it by 2:
101,543,057 ÷ 2 = 50,771,528.5
If the quotient is a whole number, then 2 and 50,771,528.5 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 | 101,543,057 | |
| -1 | -101,543,057 |
Now, we try dividing 101,543,057 by 3:
101,543,057 ÷ 3 = 33,847,685.6667
If the quotient is a whole number, then 3 and 33,847,685.6667 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 | 101,543,057 | |
| -1 | -101,543,057 |
Let's try dividing by 4:
101,543,057 ÷ 4 = 25,385,764.25
If the quotient is a whole number, then 4 and 25,385,764.25 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 | 101,543,057 | |
| -1 | 101,543,057 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 77 | 119 | 187 | 1,309 | 77,573 | 543,011 | 853,303 | 1,318,741 | 5,973,121 | 9,231,187 | 14,506,151 | 101,543,057 |
| -1 | -7 | -11 | -17 | -77 | -119 | -187 | -1,309 | -77,573 | -543,011 | -853,303 | -1,318,741 | -5,973,121 | -9,231,187 | -14,506,151 | -101,543,057 |
