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 33,478,025, 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 | 33,478,025 | |
| -1 | -33,478,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,478,025.
Example:
1 x 33,478,025 = 33,478,025
and
-1 x -33,478,025 = 33,478,025
Notice both answers equal 33,478,025
With that explanation out of the way, let's continue. Next, we take the number 33,478,025 and divide it by 2:
33,478,025 ÷ 2 = 16,739,012.5
If the quotient is a whole number, then 2 and 16,739,012.5 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 | 33,478,025 | |
| -1 | -33,478,025 |
Now, we try dividing 33,478,025 by 3:
33,478,025 ÷ 3 = 11,159,341.6667
If the quotient is a whole number, then 3 and 11,159,341.6667 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 | 33,478,025 | |
| -1 | -33,478,025 |
Let's try dividing by 4:
33,478,025 ÷ 4 = 8,369,506.25
If the quotient is a whole number, then 4 and 8,369,506.25 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 | 33,478,025 | |
| -1 | 33,478,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 1,225 | 27,329 | 136,645 | 191,303 | 683,225 | 956,515 | 1,339,121 | 4,782,575 | 6,695,605 | 33,478,025 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -1,225 | -27,329 | -136,645 | -191,303 | -683,225 | -956,515 | -1,339,121 | -4,782,575 | -6,695,605 | -33,478,025 |
