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 423,141,355, 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 | 423,141,355 | |
| -1 | -423,141,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 423,141,355.
Example:
1 x 423,141,355 = 423,141,355
and
-1 x -423,141,355 = 423,141,355
Notice both answers equal 423,141,355
With that explanation out of the way, let's continue. Next, we take the number 423,141,355 and divide it by 2:
423,141,355 ÷ 2 = 211,570,677.5
If the quotient is a whole number, then 2 and 211,570,677.5 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 | 423,141,355 | |
| -1 | -423,141,355 |
Now, we try dividing 423,141,355 by 3:
423,141,355 ÷ 3 = 141,047,118.3333
If the quotient is a whole number, then 3 and 141,047,118.3333 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 | 423,141,355 | |
| -1 | -423,141,355 |
Let's try dividing by 4:
423,141,355 ÷ 4 = 105,785,338.75
If the quotient is a whole number, then 4 and 105,785,338.75 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 | 423,141,355 | |
| -1 | 423,141,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 169 | 455 | 845 | 1,183 | 5,915 | 71,537 | 357,685 | 500,759 | 929,981 | 2,503,795 | 4,649,905 | 6,509,867 | 12,089,753 | 32,549,335 | 60,448,765 | 84,628,271 | 423,141,355 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -169 | -455 | -845 | -1,183 | -5,915 | -71,537 | -357,685 | -500,759 | -929,981 | -2,503,795 | -4,649,905 | -6,509,867 | -12,089,753 | -32,549,335 | -60,448,765 | -84,628,271 | -423,141,355 |
