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 451,064,635, 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 | 451,064,635 | |
| -1 | -451,064,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 451,064,635.
Example:
1 x 451,064,635 = 451,064,635
and
-1 x -451,064,635 = 451,064,635
Notice both answers equal 451,064,635
With that explanation out of the way, let's continue. Next, we take the number 451,064,635 and divide it by 2:
451,064,635 ÷ 2 = 225,532,317.5
If the quotient is a whole number, then 2 and 225,532,317.5 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 | 451,064,635 | |
| -1 | -451,064,635 |
Now, we try dividing 451,064,635 by 3:
451,064,635 ÷ 3 = 150,354,878.3333
If the quotient is a whole number, then 3 and 150,354,878.3333 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 | 451,064,635 | |
| -1 | -451,064,635 |
Let's try dividing by 4:
451,064,635 ÷ 4 = 112,766,158.75
If the quotient is a whole number, then 4 and 112,766,158.75 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 | 451,064,635 | |
| -1 | 451,064,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 2,063 | 6,247 | 10,315 | 14,441 | 31,235 | 43,729 | 72,205 | 218,645 | 12,887,561 | 64,437,805 | 90,212,927 | 451,064,635 |
| -1 | -5 | -7 | -35 | -2,063 | -6,247 | -10,315 | -14,441 | -31,235 | -43,729 | -72,205 | -218,645 | -12,887,561 | -64,437,805 | -90,212,927 | -451,064,635 |
