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 471,525,505, 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 | 471,525,505 | |
| -1 | -471,525,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 471,525,505.
Example:
1 x 471,525,505 = 471,525,505
and
-1 x -471,525,505 = 471,525,505
Notice both answers equal 471,525,505
With that explanation out of the way, let's continue. Next, we take the number 471,525,505 and divide it by 2:
471,525,505 ÷ 2 = 235,762,752.5
If the quotient is a whole number, then 2 and 235,762,752.5 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 | 471,525,505 | |
| -1 | -471,525,505 |
Now, we try dividing 471,525,505 by 3:
471,525,505 ÷ 3 = 157,175,168.3333
If the quotient is a whole number, then 3 and 157,175,168.3333 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 | 471,525,505 | |
| -1 | -471,525,505 |
Let's try dividing by 4:
471,525,505 ÷ 4 = 117,881,376.25
If the quotient is a whole number, then 4 and 117,881,376.25 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 | 471,525,505 | |
| -1 | 471,525,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 121 | 605 | 823 | 947 | 4,115 | 4,735 | 9,053 | 10,417 | 45,265 | 52,085 | 99,583 | 114,587 | 497,915 | 572,935 | 779,381 | 3,896,905 | 8,573,191 | 42,865,955 | 94,305,101 | 471,525,505 |
| -1 | -5 | -11 | -55 | -121 | -605 | -823 | -947 | -4,115 | -4,735 | -9,053 | -10,417 | -45,265 | -52,085 | -99,583 | -114,587 | -497,915 | -572,935 | -779,381 | -3,896,905 | -8,573,191 | -42,865,955 | -94,305,101 | -471,525,505 |
