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 141,444,355, 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 | 141,444,355 | |
| -1 | -141,444,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,444,355.
Example:
1 x 141,444,355 = 141,444,355
and
-1 x -141,444,355 = 141,444,355
Notice both answers equal 141,444,355
With that explanation out of the way, let's continue. Next, we take the number 141,444,355 and divide it by 2:
141,444,355 ÷ 2 = 70,722,177.5
If the quotient is a whole number, then 2 and 70,722,177.5 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 | 141,444,355 | |
| -1 | -141,444,355 |
Now, we try dividing 141,444,355 by 3:
141,444,355 ÷ 3 = 47,148,118.3333
If the quotient is a whole number, then 3 and 47,148,118.3333 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 | 141,444,355 | |
| -1 | -141,444,355 |
Let's try dividing by 4:
141,444,355 ÷ 4 = 35,361,088.75
If the quotient is a whole number, then 4 and 35,361,088.75 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 | 141,444,355 | |
| -1 | 141,444,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 311 | 1,555 | 4,043 | 6,997 | 20,215 | 34,985 | 90,961 | 454,805 | 2,176,067 | 10,880,335 | 28,288,871 | 141,444,355 |
| -1 | -5 | -13 | -65 | -311 | -1,555 | -4,043 | -6,997 | -20,215 | -34,985 | -90,961 | -454,805 | -2,176,067 | -10,880,335 | -28,288,871 | -141,444,355 |
