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 133,213,325, 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 | 133,213,325 | |
| -1 | -133,213,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,213,325.
Example:
1 x 133,213,325 = 133,213,325
and
-1 x -133,213,325 = 133,213,325
Notice both answers equal 133,213,325
With that explanation out of the way, let's continue. Next, we take the number 133,213,325 and divide it by 2:
133,213,325 ÷ 2 = 66,606,662.5
If the quotient is a whole number, then 2 and 66,606,662.5 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 | 133,213,325 | |
| -1 | -133,213,325 |
Now, we try dividing 133,213,325 by 3:
133,213,325 ÷ 3 = 44,404,441.6667
If the quotient is a whole number, then 3 and 44,404,441.6667 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 | 133,213,325 | |
| -1 | -133,213,325 |
Let's try dividing by 4:
133,213,325 ÷ 4 = 33,303,331.25
If the quotient is a whole number, then 4 and 33,303,331.25 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 | 133,213,325 | |
| -1 | 133,213,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 61 | 175 | 305 | 427 | 1,525 | 2,135 | 10,675 | 12,479 | 62,395 | 87,353 | 311,975 | 436,765 | 761,219 | 2,183,825 | 3,806,095 | 5,328,533 | 19,030,475 | 26,642,665 | 133,213,325 |
| -1 | -5 | -7 | -25 | -35 | -61 | -175 | -305 | -427 | -1,525 | -2,135 | -10,675 | -12,479 | -62,395 | -87,353 | -311,975 | -436,765 | -761,219 | -2,183,825 | -3,806,095 | -5,328,533 | -19,030,475 | -26,642,665 | -133,213,325 |
