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 451,451, 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 | 451,451 | |
| -1 | -451,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 451,451.
Example:
1 x 451,451 = 451,451
and
-1 x -451,451 = 451,451
Notice both answers equal 451,451
With that explanation out of the way, let's continue. Next, we take the number 451,451 and divide it by 2:
451,451 ÷ 2 = 225,725.5
If the quotient is a whole number, then 2 and 225,725.5 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 | 451,451 | |
| -1 | -451,451 |
Now, we try dividing 451,451 by 3:
451,451 ÷ 3 = 150,483.6667
If the quotient is a whole number, then 3 and 150,483.6667 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 | 451,451 | |
| -1 | -451,451 |
Let's try dividing by 4:
451,451 ÷ 4 = 112,862.75
If the quotient is a whole number, then 4 and 112,862.75 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 | 451,451 | |
| -1 | 451,451 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 41 | 77 | 91 | 121 | 143 | 287 | 451 | 533 | 847 | 1,001 | 1,573 | 3,157 | 3,731 | 4,961 | 5,863 | 11,011 | 34,727 | 41,041 | 64,493 | 451,451 |
| -1 | -7 | -11 | -13 | -41 | -77 | -91 | -121 | -143 | -287 | -451 | -533 | -847 | -1,001 | -1,573 | -3,157 | -3,731 | -4,961 | -5,863 | -11,011 | -34,727 | -41,041 | -64,493 | -451,451 |
