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 450,342,319, 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 | 450,342,319 | |
| -1 | -450,342,319 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 450,342,319.
Example:
1 x 450,342,319 = 450,342,319
and
-1 x -450,342,319 = 450,342,319
Notice both answers equal 450,342,319
With that explanation out of the way, let's continue. Next, we take the number 450,342,319 and divide it by 2:
450,342,319 ÷ 2 = 225,171,159.5
If the quotient is a whole number, then 2 and 225,171,159.5 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 | 450,342,319 | |
| -1 | -450,342,319 |
Now, we try dividing 450,342,319 by 3:
450,342,319 ÷ 3 = 150,114,106.3333
If the quotient is a whole number, then 3 and 150,114,106.3333 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 | 450,342,319 | |
| -1 | -450,342,319 |
Let's try dividing by 4:
450,342,319 ÷ 4 = 112,585,579.75
If the quotient is a whole number, then 4 and 112,585,579.75 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 | 450,342,319 | |
| -1 | 450,342,319 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 287 | 1,013 | 1,549 | 7,091 | 10,843 | 41,533 | 63,509 | 290,731 | 444,563 | 1,569,137 | 10,983,959 | 64,334,617 | 450,342,319 |
| -1 | -7 | -41 | -287 | -1,013 | -1,549 | -7,091 | -10,843 | -41,533 | -63,509 | -290,731 | -444,563 | -1,569,137 | -10,983,959 | -64,334,617 | -450,342,319 |
