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 132,152,503, 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 | 132,152,503 | |
| -1 | -132,152,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,152,503.
Example:
1 x 132,152,503 = 132,152,503
and
-1 x -132,152,503 = 132,152,503
Notice both answers equal 132,152,503
With that explanation out of the way, let's continue. Next, we take the number 132,152,503 and divide it by 2:
132,152,503 ÷ 2 = 66,076,251.5
If the quotient is a whole number, then 2 and 66,076,251.5 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 | 132,152,503 | |
| -1 | -132,152,503 |
Now, we try dividing 132,152,503 by 3:
132,152,503 ÷ 3 = 44,050,834.3333
If the quotient is a whole number, then 3 and 44,050,834.3333 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 | 132,152,503 | |
| -1 | -132,152,503 |
Let's try dividing by 4:
132,152,503 ÷ 4 = 33,038,125.75
If the quotient is a whole number, then 4 and 33,038,125.75 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 | 132,152,503 | |
| -1 | 132,152,503 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 263 | 1,841 | 3,121 | 6,049 | 21,847 | 42,343 | 71,783 | 502,481 | 820,823 | 5,745,761 | 18,878,929 | 132,152,503 |
| -1 | -7 | -23 | -161 | -263 | -1,841 | -3,121 | -6,049 | -21,847 | -42,343 | -71,783 | -502,481 | -820,823 | -5,745,761 | -18,878,929 | -132,152,503 |
