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 450,232,153, 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 | 450,232,153 | |
| -1 | -450,232,153 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 450,232,153.
Example:
1 x 450,232,153 = 450,232,153
and
-1 x -450,232,153 = 450,232,153
Notice both answers equal 450,232,153
With that explanation out of the way, let's continue. Next, we take the number 450,232,153 and divide it by 2:
450,232,153 ÷ 2 = 225,116,076.5
If the quotient is a whole number, then 2 and 225,116,076.5 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 | 450,232,153 | |
| -1 | -450,232,153 |
Now, we try dividing 450,232,153 by 3:
450,232,153 ÷ 3 = 150,077,384.3333
If the quotient is a whole number, then 3 and 150,077,384.3333 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 | 450,232,153 | |
| -1 | -450,232,153 |
Let's try dividing by 4:
450,232,153 ÷ 4 = 112,558,038.25
If the quotient is a whole number, then 4 and 112,558,038.25 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 | 450,232,153 | |
| -1 | 450,232,153 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 347 | 2,429 | 7,981 | 8,059 | 55,867 | 56,413 | 185,357 | 1,297,499 | 2,796,473 | 19,575,311 | 64,318,879 | 450,232,153 |
| -1 | -7 | -23 | -161 | -347 | -2,429 | -7,981 | -8,059 | -55,867 | -56,413 | -185,357 | -1,297,499 | -2,796,473 | -19,575,311 | -64,318,879 | -450,232,153 |
