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 70,777,661, 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 | 70,777,661 | |
| -1 | -70,777,661 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 70,777,661.
Example:
1 x 70,777,661 = 70,777,661
and
-1 x -70,777,661 = 70,777,661
Notice both answers equal 70,777,661
With that explanation out of the way, let's continue. Next, we take the number 70,777,661 and divide it by 2:
70,777,661 ÷ 2 = 35,388,830.5
If the quotient is a whole number, then 2 and 35,388,830.5 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 | 70,777,661 | |
| -1 | -70,777,661 |
Now, we try dividing 70,777,661 by 3:
70,777,661 ÷ 3 = 23,592,553.6667
If the quotient is a whole number, then 3 and 23,592,553.6667 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 | 70,777,661 | |
| -1 | -70,777,661 |
Let's try dividing by 4:
70,777,661 ÷ 4 = 17,694,415.25
If the quotient is a whole number, then 4 and 17,694,415.25 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 | 70,777,661 | |
| -1 | 70,777,661 |
If you did it right, you will end up with this table:
| 1 | 29 | 67 | 73 | 499 | 1,943 | 2,117 | 4,891 | 14,471 | 33,433 | 36,427 | 141,839 | 969,557 | 1,056,383 | 2,440,609 | 70,777,661 |
| -1 | -29 | -67 | -73 | -499 | -1,943 | -2,117 | -4,891 | -14,471 | -33,433 | -36,427 | -141,839 | -969,557 | -1,056,383 | -2,440,609 | -70,777,661 |
