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 426,373,753, 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 | 426,373,753 | |
| -1 | -426,373,753 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 426,373,753.
Example:
1 x 426,373,753 = 426,373,753
and
-1 x -426,373,753 = 426,373,753
Notice both answers equal 426,373,753
With that explanation out of the way, let's continue. Next, we take the number 426,373,753 and divide it by 2:
426,373,753 ÷ 2 = 213,186,876.5
If the quotient is a whole number, then 2 and 213,186,876.5 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 | 426,373,753 | |
| -1 | -426,373,753 |
Now, we try dividing 426,373,753 by 3:
426,373,753 ÷ 3 = 142,124,584.3333
If the quotient is a whole number, then 3 and 142,124,584.3333 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 | 426,373,753 | |
| -1 | -426,373,753 |
Let's try dividing by 4:
426,373,753 ÷ 4 = 106,593,438.25
If the quotient is a whole number, then 4 and 106,593,438.25 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 | 426,373,753 | |
| -1 | 426,373,753 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 103 | 221 | 1,339 | 1,751 | 18,731 | 22,763 | 243,503 | 318,427 | 1,929,293 | 4,139,551 | 25,080,809 | 32,797,981 | 426,373,753 |
| -1 | -13 | -17 | -103 | -221 | -1,339 | -1,751 | -18,731 | -22,763 | -243,503 | -318,427 | -1,929,293 | -4,139,551 | -25,080,809 | -32,797,981 | -426,373,753 |
