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 151,650,457, 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 | 151,650,457 | |
| -1 | -151,650,457 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,650,457.
Example:
1 x 151,650,457 = 151,650,457
and
-1 x -151,650,457 = 151,650,457
Notice both answers equal 151,650,457
With that explanation out of the way, let's continue. Next, we take the number 151,650,457 and divide it by 2:
151,650,457 ÷ 2 = 75,825,228.5
If the quotient is a whole number, then 2 and 75,825,228.5 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 | 151,650,457 | |
| -1 | -151,650,457 |
Now, we try dividing 151,650,457 by 3:
151,650,457 ÷ 3 = 50,550,152.3333
If the quotient is a whole number, then 3 and 50,550,152.3333 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 | 151,650,457 | |
| -1 | -151,650,457 |
Let's try dividing by 4:
151,650,457 ÷ 4 = 37,912,614.25
If the quotient is a whole number, then 4 and 37,912,614.25 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 | 151,650,457 | |
| -1 | 151,650,457 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 37 | 133 | 259 | 703 | 4,921 | 30,817 | 215,719 | 585,523 | 1,140,229 | 4,098,661 | 7,981,603 | 21,664,351 | 151,650,457 |
| -1 | -7 | -19 | -37 | -133 | -259 | -703 | -4,921 | -30,817 | -215,719 | -585,523 | -1,140,229 | -4,098,661 | -7,981,603 | -21,664,351 | -151,650,457 |
