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 434,152,145, 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 | 434,152,145 | |
| -1 | -434,152,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 434,152,145.
Example:
1 x 434,152,145 = 434,152,145
and
-1 x -434,152,145 = 434,152,145
Notice both answers equal 434,152,145
With that explanation out of the way, let's continue. Next, we take the number 434,152,145 and divide it by 2:
434,152,145 ÷ 2 = 217,076,072.5
If the quotient is a whole number, then 2 and 217,076,072.5 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 | 434,152,145 | |
| -1 | -434,152,145 |
Now, we try dividing 434,152,145 by 3:
434,152,145 ÷ 3 = 144,717,381.6667
If the quotient is a whole number, then 3 and 144,717,381.6667 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 | 434,152,145 | |
| -1 | -434,152,145 |
Let's try dividing by 4:
434,152,145 ÷ 4 = 108,538,036.25
If the quotient is a whole number, then 4 and 108,538,036.25 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 | 434,152,145 | |
| -1 | 434,152,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 991 | 4,955 | 6,937 | 12,517 | 34,685 | 62,585 | 87,619 | 438,095 | 12,404,347 | 62,021,735 | 86,830,429 | 434,152,145 |
| -1 | -5 | -7 | -35 | -991 | -4,955 | -6,937 | -12,517 | -34,685 | -62,585 | -87,619 | -438,095 | -12,404,347 | -62,021,735 | -86,830,429 | -434,152,145 |
