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 151,354,255, 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 | 151,354,255 | |
| -1 | -151,354,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,354,255.
Example:
1 x 151,354,255 = 151,354,255
and
-1 x -151,354,255 = 151,354,255
Notice both answers equal 151,354,255
With that explanation out of the way, let's continue. Next, we take the number 151,354,255 and divide it by 2:
151,354,255 ÷ 2 = 75,677,127.5
If the quotient is a whole number, then 2 and 75,677,127.5 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 | 151,354,255 | |
| -1 | -151,354,255 |
Now, we try dividing 151,354,255 by 3:
151,354,255 ÷ 3 = 50,451,418.3333
If the quotient is a whole number, then 3 and 50,451,418.3333 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 | 151,354,255 | |
| -1 | -151,354,255 |
Let's try dividing by 4:
151,354,255 ÷ 4 = 37,838,563.75
If the quotient is a whole number, then 4 and 37,838,563.75 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 | 151,354,255 | |
| -1 | 151,354,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 251 | 1,255 | 3,263 | 9,277 | 16,315 | 46,385 | 120,601 | 603,005 | 2,328,527 | 11,642,635 | 30,270,851 | 151,354,255 |
| -1 | -5 | -13 | -65 | -251 | -1,255 | -3,263 | -9,277 | -16,315 | -46,385 | -120,601 | -603,005 | -2,328,527 | -11,642,635 | -30,270,851 | -151,354,255 |
