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 151,054,225, 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 | 151,054,225 | |
| -1 | -151,054,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,054,225.
Example:
1 x 151,054,225 = 151,054,225
and
-1 x -151,054,225 = 151,054,225
Notice both answers equal 151,054,225
With that explanation out of the way, let's continue. Next, we take the number 151,054,225 and divide it by 2:
151,054,225 ÷ 2 = 75,527,112.5
If the quotient is a whole number, then 2 and 75,527,112.5 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 | 151,054,225 | |
| -1 | -151,054,225 |
Now, we try dividing 151,054,225 by 3:
151,054,225 ÷ 3 = 50,351,408.3333
If the quotient is a whole number, then 3 and 50,351,408.3333 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 | 151,054,225 | |
| -1 | -151,054,225 |
Let's try dividing by 4:
151,054,225 ÷ 4 = 37,763,556.25
If the quotient is a whole number, then 4 and 37,763,556.25 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 | 151,054,225 | |
| -1 | 151,054,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 25 | 35 | 115 | 161 | 175 | 575 | 805 | 4,025 | 37,529 | 187,645 | 262,703 | 863,167 | 938,225 | 1,313,515 | 4,315,835 | 6,042,169 | 6,567,575 | 21,579,175 | 30,210,845 | 151,054,225 |
| -1 | -5 | -7 | -23 | -25 | -35 | -115 | -161 | -175 | -575 | -805 | -4,025 | -37,529 | -187,645 | -262,703 | -863,167 | -938,225 | -1,313,515 | -4,315,835 | -6,042,169 | -6,567,575 | -21,579,175 | -30,210,845 | -151,054,225 |
