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 434,620,445, 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 | 434,620,445 | |
| -1 | -434,620,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 434,620,445.
Example:
1 x 434,620,445 = 434,620,445
and
-1 x -434,620,445 = 434,620,445
Notice both answers equal 434,620,445
With that explanation out of the way, let's continue. Next, we take the number 434,620,445 and divide it by 2:
434,620,445 ÷ 2 = 217,310,222.5
If the quotient is a whole number, then 2 and 217,310,222.5 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 | 434,620,445 | |
| -1 | -434,620,445 |
Now, we try dividing 434,620,445 by 3:
434,620,445 ÷ 3 = 144,873,481.6667
If the quotient is a whole number, then 3 and 144,873,481.6667 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 | 434,620,445 | |
| -1 | -434,620,445 |
Let's try dividing by 4:
434,620,445 ÷ 4 = 108,655,111.25
If the quotient is a whole number, then 4 and 108,655,111.25 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 | 434,620,445 | |
| -1 | 434,620,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 343 | 1,715 | 253,423 | 1,267,115 | 1,773,961 | 8,869,805 | 12,417,727 | 62,088,635 | 86,924,089 | 434,620,445 |
| -1 | -5 | -7 | -35 | -49 | -245 | -343 | -1,715 | -253,423 | -1,267,115 | -1,773,961 | -8,869,805 | -12,417,727 | -62,088,635 | -86,924,089 | -434,620,445 |
