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 151,411,375, 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 | 151,411,375 | |
| -1 | -151,411,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,411,375.
Example:
1 x 151,411,375 = 151,411,375
and
-1 x -151,411,375 = 151,411,375
Notice both answers equal 151,411,375
With that explanation out of the way, let's continue. Next, we take the number 151,411,375 and divide it by 2:
151,411,375 ÷ 2 = 75,705,687.5
If the quotient is a whole number, then 2 and 75,705,687.5 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 | 151,411,375 | |
| -1 | -151,411,375 |
Now, we try dividing 151,411,375 by 3:
151,411,375 ÷ 3 = 50,470,458.3333
If the quotient is a whole number, then 3 and 50,470,458.3333 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 | 151,411,375 | |
| -1 | -151,411,375 |
Let's try dividing by 4:
151,411,375 ÷ 4 = 37,852,843.75
If the quotient is a whole number, then 4 and 37,852,843.75 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 | 151,411,375 | |
| -1 | 151,411,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 773 | 1,567 | 3,865 | 7,835 | 19,325 | 39,175 | 96,625 | 195,875 | 1,211,291 | 6,056,455 | 30,282,275 | 151,411,375 |
| -1 | -5 | -25 | -125 | -773 | -1,567 | -3,865 | -7,835 | -19,325 | -39,175 | -96,625 | -195,875 | -1,211,291 | -6,056,455 | -30,282,275 | -151,411,375 |
