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 451,460,045, 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 | 451,460,045 | |
| -1 | -451,460,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 451,460,045.
Example:
1 x 451,460,045 = 451,460,045
and
-1 x -451,460,045 = 451,460,045
Notice both answers equal 451,460,045
With that explanation out of the way, let's continue. Next, we take the number 451,460,045 and divide it by 2:
451,460,045 ÷ 2 = 225,730,022.5
If the quotient is a whole number, then 2 and 225,730,022.5 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 | 451,460,045 | |
| -1 | -451,460,045 |
Now, we try dividing 451,460,045 by 3:
451,460,045 ÷ 3 = 150,486,681.6667
If the quotient is a whole number, then 3 and 150,486,681.6667 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 | 451,460,045 | |
| -1 | -451,460,045 |
Let's try dividing by 4:
451,460,045 ÷ 4 = 112,865,011.25
If the quotient is a whole number, then 4 and 112,865,011.25 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 | 451,460,045 | |
| -1 | 451,460,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 1,637 | 2,903 | 8,185 | 14,515 | 31,103 | 55,157 | 155,515 | 275,785 | 4,752,211 | 23,761,055 | 90,292,009 | 451,460,045 |
| -1 | -5 | -19 | -95 | -1,637 | -2,903 | -8,185 | -14,515 | -31,103 | -55,157 | -155,515 | -275,785 | -4,752,211 | -23,761,055 | -90,292,009 | -451,460,045 |
