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 132,877,003, 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 | 132,877,003 | |
| -1 | -132,877,003 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,877,003.
Example:
1 x 132,877,003 = 132,877,003
and
-1 x -132,877,003 = 132,877,003
Notice both answers equal 132,877,003
With that explanation out of the way, let's continue. Next, we take the number 132,877,003 and divide it by 2:
132,877,003 ÷ 2 = 66,438,501.5
If the quotient is a whole number, then 2 and 66,438,501.5 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 | 132,877,003 | |
| -1 | -132,877,003 |
Now, we try dividing 132,877,003 by 3:
132,877,003 ÷ 3 = 44,292,334.3333
If the quotient is a whole number, then 3 and 44,292,334.3333 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 | 132,877,003 | |
| -1 | -132,877,003 |
Let's try dividing by 4:
132,877,003 ÷ 4 = 33,219,250.75
If the quotient is a whole number, then 4 and 33,219,250.75 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 | 132,877,003 | |
| -1 | 132,877,003 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 223 | 1,561 | 3,701 | 5,129 | 25,907 | 35,903 | 85,123 | 595,861 | 825,323 | 5,777,261 | 18,982,429 | 132,877,003 |
| -1 | -7 | -23 | -161 | -223 | -1,561 | -3,701 | -5,129 | -25,907 | -35,903 | -85,123 | -595,861 | -825,323 | -5,777,261 | -18,982,429 | -132,877,003 |
