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 551,523,125, 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 | 551,523,125 | |
| -1 | -551,523,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 551,523,125.
Example:
1 x 551,523,125 = 551,523,125
and
-1 x -551,523,125 = 551,523,125
Notice both answers equal 551,523,125
With that explanation out of the way, let's continue. Next, we take the number 551,523,125 and divide it by 2:
551,523,125 ÷ 2 = 275,761,562.5
If the quotient is a whole number, then 2 and 275,761,562.5 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 | 551,523,125 | |
| -1 | -551,523,125 |
Now, we try dividing 551,523,125 by 3:
551,523,125 ÷ 3 = 183,841,041.6667
If the quotient is a whole number, then 3 and 183,841,041.6667 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 | 551,523,125 | |
| -1 | -551,523,125 |
Let's try dividing by 4:
551,523,125 ÷ 4 = 137,880,781.25
If the quotient is a whole number, then 4 and 137,880,781.25 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 | 551,523,125 | |
| -1 | 551,523,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 101 | 125 | 505 | 625 | 2,525 | 8,737 | 12,625 | 43,685 | 63,125 | 218,425 | 882,437 | 1,092,125 | 4,412,185 | 5,460,625 | 22,060,925 | 110,304,625 | 551,523,125 |
| -1 | -5 | -25 | -101 | -125 | -505 | -625 | -2,525 | -8,737 | -12,625 | -43,685 | -63,125 | -218,425 | -882,437 | -1,092,125 | -4,412,185 | -5,460,625 | -22,060,925 | -110,304,625 | -551,523,125 |
