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 77,413,609, 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 | 77,413,609 | |
| -1 | -77,413,609 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 77,413,609.
Example:
1 x 77,413,609 = 77,413,609
and
-1 x -77,413,609 = 77,413,609
Notice both answers equal 77,413,609
With that explanation out of the way, let's continue. Next, we take the number 77,413,609 and divide it by 2:
77,413,609 ÷ 2 = 38,706,804.5
If the quotient is a whole number, then 2 and 38,706,804.5 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 | 77,413,609 | |
| -1 | -77,413,609 |
Now, we try dividing 77,413,609 by 3:
77,413,609 ÷ 3 = 25,804,536.3333
If the quotient is a whole number, then 3 and 25,804,536.3333 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 | 77,413,609 | |
| -1 | -77,413,609 |
Let's try dividing by 4:
77,413,609 ÷ 4 = 19,353,402.25
If the quotient is a whole number, then 4 and 19,353,402.25 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 | 77,413,609 | |
| -1 | 77,413,609 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 67 | 91 | 469 | 871 | 6,097 | 12,697 | 88,879 | 165,061 | 850,699 | 1,155,427 | 5,954,893 | 11,059,087 | 77,413,609 |
| -1 | -7 | -13 | -67 | -91 | -469 | -871 | -6,097 | -12,697 | -88,879 | -165,061 | -850,699 | -1,155,427 | -5,954,893 | -11,059,087 | -77,413,609 |
