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 763,641,823, 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 | 763,641,823 | |
| -1 | -763,641,823 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 763,641,823.
Example:
1 x 763,641,823 = 763,641,823
and
-1 x -763,641,823 = 763,641,823
Notice both answers equal 763,641,823
With that explanation out of the way, let's continue. Next, we take the number 763,641,823 and divide it by 2:
763,641,823 ÷ 2 = 381,820,911.5
If the quotient is a whole number, then 2 and 381,820,911.5 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 | 763,641,823 | |
| -1 | -763,641,823 |
Now, we try dividing 763,641,823 by 3:
763,641,823 ÷ 3 = 254,547,274.3333
If the quotient is a whole number, then 3 and 254,547,274.3333 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 | 763,641,823 | |
| -1 | -763,641,823 |
Let's try dividing by 4:
763,641,823 ÷ 4 = 190,910,455.75
If the quotient is a whole number, then 4 and 190,910,455.75 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 | 763,641,823 | |
| -1 | 763,641,823 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 283 | 343 | 1,981 | 7,867 | 13,867 | 55,069 | 97,069 | 385,483 | 2,226,361 | 2,698,381 | 15,584,527 | 109,091,689 | 763,641,823 |
| -1 | -7 | -49 | -283 | -343 | -1,981 | -7,867 | -13,867 | -55,069 | -97,069 | -385,483 | -2,226,361 | -2,698,381 | -15,584,527 | -109,091,689 | -763,641,823 |
