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 51,223,465, 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 | 51,223,465 | |
| -1 | -51,223,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,223,465.
Example:
1 x 51,223,465 = 51,223,465
and
-1 x -51,223,465 = 51,223,465
Notice both answers equal 51,223,465
With that explanation out of the way, let's continue. Next, we take the number 51,223,465 and divide it by 2:
51,223,465 ÷ 2 = 25,611,732.5
If the quotient is a whole number, then 2 and 25,611,732.5 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 | 51,223,465 | |
| -1 | -51,223,465 |
Now, we try dividing 51,223,465 by 3:
51,223,465 ÷ 3 = 17,074,488.3333
If the quotient is a whole number, then 3 and 17,074,488.3333 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 | 51,223,465 | |
| -1 | -51,223,465 |
Let's try dividing by 4:
51,223,465 ÷ 4 = 12,805,866.25
If the quotient is a whole number, then 4 and 12,805,866.25 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 | 51,223,465 | |
| -1 | 51,223,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 113 | 565 | 1,921 | 5,333 | 9,605 | 26,665 | 90,661 | 453,305 | 602,629 | 3,013,145 | 10,244,693 | 51,223,465 |
| -1 | -5 | -17 | -85 | -113 | -565 | -1,921 | -5,333 | -9,605 | -26,665 | -90,661 | -453,305 | -602,629 | -3,013,145 | -10,244,693 | -51,223,465 |
