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 770,003,143, 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 | 770,003,143 | |
| -1 | -770,003,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 770,003,143.
Example:
1 x 770,003,143 = 770,003,143
and
-1 x -770,003,143 = 770,003,143
Notice both answers equal 770,003,143
With that explanation out of the way, let's continue. Next, we take the number 770,003,143 and divide it by 2:
770,003,143 ÷ 2 = 385,001,571.5
If the quotient is a whole number, then 2 and 385,001,571.5 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 | 770,003,143 | |
| -1 | -770,003,143 |
Now, we try dividing 770,003,143 by 3:
770,003,143 ÷ 3 = 256,667,714.3333
If the quotient is a whole number, then 3 and 256,667,714.3333 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 | 770,003,143 | |
| -1 | -770,003,143 |
Let's try dividing by 4:
770,003,143 ÷ 4 = 192,500,785.75
If the quotient is a whole number, then 4 and 192,500,785.75 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 | 770,003,143 | |
| -1 | 770,003,143 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 467 | 3,269 | 6,071 | 18,119 | 42,497 | 126,833 | 235,547 | 1,648,829 | 8,461,573 | 59,231,011 | 110,000,449 | 770,003,143 |
| -1 | -7 | -13 | -91 | -467 | -3,269 | -6,071 | -18,119 | -42,497 | -126,833 | -235,547 | -1,648,829 | -8,461,573 | -59,231,011 | -110,000,449 | -770,003,143 |
