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 35,401,255, 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 | 35,401,255 | |
| -1 | -35,401,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 35,401,255.
Example:
1 x 35,401,255 = 35,401,255
and
-1 x -35,401,255 = 35,401,255
Notice both answers equal 35,401,255
With that explanation out of the way, let's continue. Next, we take the number 35,401,255 and divide it by 2:
35,401,255 ÷ 2 = 17,700,627.5
If the quotient is a whole number, then 2 and 17,700,627.5 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 | 35,401,255 | |
| -1 | -35,401,255 |
Now, we try dividing 35,401,255 by 3:
35,401,255 ÷ 3 = 11,800,418.3333
If the quotient is a whole number, then 3 and 11,800,418.3333 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 | 35,401,255 | |
| -1 | -35,401,255 |
Let's try dividing by 4:
35,401,255 ÷ 4 = 8,850,313.75
If the quotient is a whole number, then 4 and 8,850,313.75 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 | 35,401,255 | |
| -1 | 35,401,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 43 | 115 | 215 | 989 | 4,945 | 7,159 | 35,795 | 164,657 | 307,837 | 823,285 | 1,539,185 | 7,080,251 | 35,401,255 |
| -1 | -5 | -23 | -43 | -115 | -215 | -989 | -4,945 | -7,159 | -35,795 | -164,657 | -307,837 | -823,285 | -1,539,185 | -7,080,251 | -35,401,255 |
