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 751,766,323, 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 | 751,766,323 | |
| -1 | -751,766,323 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 751,766,323.
Example:
1 x 751,766,323 = 751,766,323
and
-1 x -751,766,323 = 751,766,323
Notice both answers equal 751,766,323
With that explanation out of the way, let's continue. Next, we take the number 751,766,323 and divide it by 2:
751,766,323 ÷ 2 = 375,883,161.5
If the quotient is a whole number, then 2 and 375,883,161.5 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 | 751,766,323 | |
| -1 | -751,766,323 |
Now, we try dividing 751,766,323 by 3:
751,766,323 ÷ 3 = 250,588,774.3333
If the quotient is a whole number, then 3 and 250,588,774.3333 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 | 751,766,323 | |
| -1 | -751,766,323 |
Let's try dividing by 4:
751,766,323 ÷ 4 = 187,941,580.75
If the quotient is a whole number, then 4 and 187,941,580.75 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 | 751,766,323 | |
| -1 | 751,766,323 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 2,917 | 3,347 | 20,419 | 23,429 | 32,087 | 36,817 | 224,609 | 257,719 | 9,763,199 | 68,342,393 | 107,395,189 | 751,766,323 |
| -1 | -7 | -11 | -77 | -2,917 | -3,347 | -20,419 | -23,429 | -32,087 | -36,817 | -224,609 | -257,719 | -9,763,199 | -68,342,393 | -107,395,189 | -751,766,323 |
