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 66,752,635, 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 | 66,752,635 | |
| -1 | -66,752,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 66,752,635.
Example:
1 x 66,752,635 = 66,752,635
and
-1 x -66,752,635 = 66,752,635
Notice both answers equal 66,752,635
With that explanation out of the way, let's continue. Next, we take the number 66,752,635 and divide it by 2:
66,752,635 ÷ 2 = 33,376,317.5
If the quotient is a whole number, then 2 and 33,376,317.5 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 | 66,752,635 | |
| -1 | -66,752,635 |
Now, we try dividing 66,752,635 by 3:
66,752,635 ÷ 3 = 22,250,878.3333
If the quotient is a whole number, then 3 and 22,250,878.3333 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 | 66,752,635 | |
| -1 | -66,752,635 |
Let's try dividing by 4:
66,752,635 ÷ 4 = 16,688,158.75
If the quotient is a whole number, then 4 and 16,688,158.75 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 | 66,752,635 | |
| -1 | 66,752,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 613 | 751 | 3,065 | 3,755 | 17,777 | 21,779 | 88,885 | 108,895 | 460,363 | 2,301,815 | 13,350,527 | 66,752,635 |
| -1 | -5 | -29 | -145 | -613 | -751 | -3,065 | -3,755 | -17,777 | -21,779 | -88,885 | -108,895 | -460,363 | -2,301,815 | -13,350,527 | -66,752,635 |
