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 141,077,605, 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 | 141,077,605 | |
| -1 | -141,077,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 141,077,605.
Example:
1 x 141,077,605 = 141,077,605
and
-1 x -141,077,605 = 141,077,605
Notice both answers equal 141,077,605
With that explanation out of the way, let's continue. Next, we take the number 141,077,605 and divide it by 2:
141,077,605 ÷ 2 = 70,538,802.5
If the quotient is a whole number, then 2 and 70,538,802.5 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 | 141,077,605 | |
| -1 | -141,077,605 |
Now, we try dividing 141,077,605 by 3:
141,077,605 ÷ 3 = 47,025,868.3333
If the quotient is a whole number, then 3 and 47,025,868.3333 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 | 141,077,605 | |
| -1 | -141,077,605 |
Let's try dividing by 4:
141,077,605 ÷ 4 = 35,269,401.25
If the quotient is a whole number, then 4 and 35,269,401.25 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 | 141,077,605 | |
| -1 | 141,077,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 223 | 1,115 | 4,363 | 6,467 | 21,815 | 32,335 | 126,527 | 632,635 | 972,949 | 4,864,745 | 28,215,521 | 141,077,605 |
| -1 | -5 | -29 | -145 | -223 | -1,115 | -4,363 | -6,467 | -21,815 | -32,335 | -126,527 | -632,635 | -972,949 | -4,864,745 | -28,215,521 | -141,077,605 |
