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 150,513,025, 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 | 150,513,025 | |
| -1 | -150,513,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,513,025.
Example:
1 x 150,513,025 = 150,513,025
and
-1 x -150,513,025 = 150,513,025
Notice both answers equal 150,513,025
With that explanation out of the way, let's continue. Next, we take the number 150,513,025 and divide it by 2:
150,513,025 ÷ 2 = 75,256,512.5
If the quotient is a whole number, then 2 and 75,256,512.5 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 | 150,513,025 | |
| -1 | -150,513,025 |
Now, we try dividing 150,513,025 by 3:
150,513,025 ÷ 3 = 50,171,008.3333
If the quotient is a whole number, then 3 and 50,171,008.3333 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 | 150,513,025 | |
| -1 | -150,513,025 |
Let's try dividing by 4:
150,513,025 ÷ 4 = 37,628,256.25
If the quotient is a whole number, then 4 and 37,628,256.25 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 | 150,513,025 | |
| -1 | 150,513,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 151 | 325 | 755 | 1,963 | 3,067 | 3,775 | 9,815 | 15,335 | 39,871 | 49,075 | 76,675 | 199,355 | 463,117 | 996,775 | 2,315,585 | 6,020,521 | 11,577,925 | 30,102,605 | 150,513,025 |
| -1 | -5 | -13 | -25 | -65 | -151 | -325 | -755 | -1,963 | -3,067 | -3,775 | -9,815 | -15,335 | -39,871 | -49,075 | -76,675 | -199,355 | -463,117 | -996,775 | -2,315,585 | -6,020,521 | -11,577,925 | -30,102,605 | -150,513,025 |
