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 762,730,445, 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 | 762,730,445 | |
| -1 | -762,730,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 762,730,445.
Example:
1 x 762,730,445 = 762,730,445
and
-1 x -762,730,445 = 762,730,445
Notice both answers equal 762,730,445
With that explanation out of the way, let's continue. Next, we take the number 762,730,445 and divide it by 2:
762,730,445 ÷ 2 = 381,365,222.5
If the quotient is a whole number, then 2 and 381,365,222.5 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 | 762,730,445 | |
| -1 | -762,730,445 |
Now, we try dividing 762,730,445 by 3:
762,730,445 ÷ 3 = 254,243,481.6667
If the quotient is a whole number, then 3 and 254,243,481.6667 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 | 762,730,445 | |
| -1 | -762,730,445 |
Let's try dividing by 4:
762,730,445 ÷ 4 = 190,682,611.25
If the quotient is a whole number, then 4 and 190,682,611.25 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 | 762,730,445 | |
| -1 | 762,730,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 89 | 151 | 445 | 755 | 11,351 | 13,439 | 56,755 | 67,195 | 1,010,239 | 1,714,001 | 5,051,195 | 8,570,005 | 152,546,089 | 762,730,445 |
| -1 | -5 | -89 | -151 | -445 | -755 | -11,351 | -13,439 | -56,755 | -67,195 | -1,010,239 | -1,714,001 | -5,051,195 | -8,570,005 | -152,546,089 | -762,730,445 |
