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 173,064,451, 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 | 173,064,451 | |
| -1 | -173,064,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 173,064,451.
Example:
1 x 173,064,451 = 173,064,451
and
-1 x -173,064,451 = 173,064,451
Notice both answers equal 173,064,451
With that explanation out of the way, let's continue. Next, we take the number 173,064,451 and divide it by 2:
173,064,451 ÷ 2 = 86,532,225.5
If the quotient is a whole number, then 2 and 86,532,225.5 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 | 173,064,451 | |
| -1 | -173,064,451 |
Now, we try dividing 173,064,451 by 3:
173,064,451 ÷ 3 = 57,688,150.3333
If the quotient is a whole number, then 3 and 57,688,150.3333 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 | 173,064,451 | |
| -1 | -173,064,451 |
Let's try dividing by 4:
173,064,451 ÷ 4 = 43,266,112.75
If the quotient is a whole number, then 4 and 43,266,112.75 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 | 173,064,451 | |
| -1 | 173,064,451 |
If you did it right, you will end up with this table:
| 1 | 7 | 53 | 193 | 371 | 1,351 | 2,417 | 10,229 | 16,919 | 71,603 | 128,101 | 466,481 | 896,707 | 3,265,367 | 24,723,493 | 173,064,451 |
| -1 | -7 | -53 | -193 | -371 | -1,351 | -2,417 | -10,229 | -16,919 | -71,603 | -128,101 | -466,481 | -896,707 | -3,265,367 | -24,723,493 | -173,064,451 |
