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 51,520,667, 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 | 51,520,667 | |
| -1 | -51,520,667 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,520,667.
Example:
1 x 51,520,667 = 51,520,667
and
-1 x -51,520,667 = 51,520,667
Notice both answers equal 51,520,667
With that explanation out of the way, let's continue. Next, we take the number 51,520,667 and divide it by 2:
51,520,667 ÷ 2 = 25,760,333.5
If the quotient is a whole number, then 2 and 25,760,333.5 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 | 51,520,667 | |
| -1 | -51,520,667 |
Now, we try dividing 51,520,667 by 3:
51,520,667 ÷ 3 = 17,173,555.6667
If the quotient is a whole number, then 3 and 17,173,555.6667 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 | 51,520,667 | |
| -1 | -51,520,667 |
Let's try dividing by 4:
51,520,667 ÷ 4 = 12,880,166.75
If the quotient is a whole number, then 4 and 12,880,166.75 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 | 51,520,667 | |
| -1 | 51,520,667 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 31 | 253 | 341 | 713 | 6,569 | 7,843 | 72,259 | 151,087 | 203,639 | 1,661,957 | 2,240,029 | 4,683,697 | 51,520,667 |
| -1 | -11 | -23 | -31 | -253 | -341 | -713 | -6,569 | -7,843 | -72,259 | -151,087 | -203,639 | -1,661,957 | -2,240,029 | -4,683,697 | -51,520,667 |
