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 424,232,545, 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 | 424,232,545 | |
| -1 | -424,232,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 424,232,545.
Example:
1 x 424,232,545 = 424,232,545
and
-1 x -424,232,545 = 424,232,545
Notice both answers equal 424,232,545
With that explanation out of the way, let's continue. Next, we take the number 424,232,545 and divide it by 2:
424,232,545 ÷ 2 = 212,116,272.5
If the quotient is a whole number, then 2 and 212,116,272.5 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 | 424,232,545 | |
| -1 | -424,232,545 |
Now, we try dividing 424,232,545 by 3:
424,232,545 ÷ 3 = 141,410,848.3333
If the quotient is a whole number, then 3 and 141,410,848.3333 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 | 424,232,545 | |
| -1 | -424,232,545 |
Let's try dividing by 4:
424,232,545 ÷ 4 = 106,058,136.25
If the quotient is a whole number, then 4 and 106,058,136.25 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 | 424,232,545 | |
| -1 | 424,232,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 1,321 | 5,839 | 6,605 | 14,531 | 29,195 | 64,229 | 72,655 | 321,145 | 7,713,319 | 38,566,595 | 84,846,509 | 424,232,545 |
| -1 | -5 | -11 | -55 | -1,321 | -5,839 | -6,605 | -14,531 | -29,195 | -64,229 | -72,655 | -321,145 | -7,713,319 | -38,566,595 | -84,846,509 | -424,232,545 |
