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 426,432,307, 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 | 426,432,307 | |
| -1 | -426,432,307 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 426,432,307.
Example:
1 x 426,432,307 = 426,432,307
and
-1 x -426,432,307 = 426,432,307
Notice both answers equal 426,432,307
With that explanation out of the way, let's continue. Next, we take the number 426,432,307 and divide it by 2:
426,432,307 ÷ 2 = 213,216,153.5
If the quotient is a whole number, then 2 and 213,216,153.5 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 | 426,432,307 | |
| -1 | -426,432,307 |
Now, we try dividing 426,432,307 by 3:
426,432,307 ÷ 3 = 142,144,102.3333
If the quotient is a whole number, then 3 and 142,144,102.3333 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 | 426,432,307 | |
| -1 | -426,432,307 |
Let's try dividing by 4:
426,432,307 ÷ 4 = 106,608,076.75
If the quotient is a whole number, then 4 and 106,608,076.75 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 | 426,432,307 | |
| -1 | 426,432,307 |
If you did it right, you will end up with this table:
| 1 | 7 | 109 | 197 | 763 | 1,379 | 2,837 | 19,859 | 21,473 | 150,311 | 309,233 | 558,889 | 2,164,631 | 3,912,223 | 60,918,901 | 426,432,307 |
| -1 | -7 | -109 | -197 | -763 | -1,379 | -2,837 | -19,859 | -21,473 | -150,311 | -309,233 | -558,889 | -2,164,631 | -3,912,223 | -60,918,901 | -426,432,307 |
