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 132,486,457, 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 | 132,486,457 | |
| -1 | -132,486,457 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,486,457.
Example:
1 x 132,486,457 = 132,486,457
and
-1 x -132,486,457 = 132,486,457
Notice both answers equal 132,486,457
With that explanation out of the way, let's continue. Next, we take the number 132,486,457 and divide it by 2:
132,486,457 ÷ 2 = 66,243,228.5
If the quotient is a whole number, then 2 and 66,243,228.5 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 | 132,486,457 | |
| -1 | -132,486,457 |
Now, we try dividing 132,486,457 by 3:
132,486,457 ÷ 3 = 44,162,152.3333
If the quotient is a whole number, then 3 and 44,162,152.3333 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 | 132,486,457 | |
| -1 | -132,486,457 |
Let's try dividing by 4:
132,486,457 ÷ 4 = 33,121,614.25
If the quotient is a whole number, then 4 and 33,121,614.25 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 | 132,486,457 | |
| -1 | 132,486,457 |
If you did it right, you will end up with this table:
| 1 | 17 | 41 | 131 | 697 | 1,451 | 2,227 | 5,371 | 24,667 | 59,491 | 91,307 | 190,081 | 1,011,347 | 3,231,377 | 7,793,321 | 132,486,457 |
| -1 | -17 | -41 | -131 | -697 | -1,451 | -2,227 | -5,371 | -24,667 | -59,491 | -91,307 | -190,081 | -1,011,347 | -3,231,377 | -7,793,321 | -132,486,457 |
