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 133,443,475, 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 | 133,443,475 | |
| -1 | -133,443,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,443,475.
Example:
1 x 133,443,475 = 133,443,475
and
-1 x -133,443,475 = 133,443,475
Notice both answers equal 133,443,475
With that explanation out of the way, let's continue. Next, we take the number 133,443,475 and divide it by 2:
133,443,475 ÷ 2 = 66,721,737.5
If the quotient is a whole number, then 2 and 66,721,737.5 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 | 133,443,475 | |
| -1 | -133,443,475 |
Now, we try dividing 133,443,475 by 3:
133,443,475 ÷ 3 = 44,481,158.3333
If the quotient is a whole number, then 3 and 44,481,158.3333 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 | 133,443,475 | |
| -1 | -133,443,475 |
Let's try dividing by 4:
133,443,475 ÷ 4 = 33,360,868.75
If the quotient is a whole number, then 4 and 33,360,868.75 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 | 133,443,475 | |
| -1 | 133,443,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 139 | 275 | 695 | 1,529 | 3,475 | 3,491 | 7,645 | 17,455 | 38,225 | 38,401 | 87,275 | 192,005 | 485,249 | 960,025 | 2,426,245 | 5,337,739 | 12,131,225 | 26,688,695 | 133,443,475 |
| -1 | -5 | -11 | -25 | -55 | -139 | -275 | -695 | -1,529 | -3,475 | -3,491 | -7,645 | -17,455 | -38,225 | -38,401 | -87,275 | -192,005 | -485,249 | -960,025 | -2,426,245 | -5,337,739 | -12,131,225 | -26,688,695 | -133,443,475 |
