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 76,470,335, 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 | 76,470,335 | |
| -1 | -76,470,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 76,470,335.
Example:
1 x 76,470,335 = 76,470,335
and
-1 x -76,470,335 = 76,470,335
Notice both answers equal 76,470,335
With that explanation out of the way, let's continue. Next, we take the number 76,470,335 and divide it by 2:
76,470,335 ÷ 2 = 38,235,167.5
If the quotient is a whole number, then 2 and 38,235,167.5 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 | 76,470,335 | |
| -1 | -76,470,335 |
Now, we try dividing 76,470,335 by 3:
76,470,335 ÷ 3 = 25,490,111.6667
If the quotient is a whole number, then 3 and 25,490,111.6667 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 | 76,470,335 | |
| -1 | -76,470,335 |
Let's try dividing by 4:
76,470,335 ÷ 4 = 19,117,583.75
If the quotient is a whole number, then 4 and 19,117,583.75 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 | 76,470,335 | |
| -1 | 76,470,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 31 | 85 | 155 | 527 | 2,635 | 29,021 | 145,105 | 493,357 | 899,651 | 2,466,785 | 4,498,255 | 15,294,067 | 76,470,335 |
| -1 | -5 | -17 | -31 | -85 | -155 | -527 | -2,635 | -29,021 | -145,105 | -493,357 | -899,651 | -2,466,785 | -4,498,255 | -15,294,067 | -76,470,335 |
