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 133,523,425, 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 | 133,523,425 | |
| -1 | -133,523,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,523,425.
Example:
1 x 133,523,425 = 133,523,425
and
-1 x -133,523,425 = 133,523,425
Notice both answers equal 133,523,425
With that explanation out of the way, let's continue. Next, we take the number 133,523,425 and divide it by 2:
133,523,425 ÷ 2 = 66,761,712.5
If the quotient is a whole number, then 2 and 66,761,712.5 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 | 133,523,425 | |
| -1 | -133,523,425 |
Now, we try dividing 133,523,425 by 3:
133,523,425 ÷ 3 = 44,507,808.3333
If the quotient is a whole number, then 3 and 44,507,808.3333 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 | 133,523,425 | |
| -1 | -133,523,425 |
Let's try dividing by 4:
133,523,425 ÷ 4 = 33,380,856.25
If the quotient is a whole number, then 4 and 33,380,856.25 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 | 133,523,425 | |
| -1 | 133,523,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 509 | 1,499 | 2,545 | 3,563 | 7,495 | 10,493 | 12,725 | 17,815 | 37,475 | 52,465 | 89,075 | 262,325 | 762,991 | 3,814,955 | 5,340,937 | 19,074,775 | 26,704,685 | 133,523,425 |
| -1 | -5 | -7 | -25 | -35 | -175 | -509 | -1,499 | -2,545 | -3,563 | -7,495 | -10,493 | -12,725 | -17,815 | -37,475 | -52,465 | -89,075 | -262,325 | -762,991 | -3,814,955 | -5,340,937 | -19,074,775 | -26,704,685 | -133,523,425 |
