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 234,818,143, 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 | 234,818,143 | |
| -1 | -234,818,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 234,818,143.
Example:
1 x 234,818,143 = 234,818,143
and
-1 x -234,818,143 = 234,818,143
Notice both answers equal 234,818,143
With that explanation out of the way, let's continue. Next, we take the number 234,818,143 and divide it by 2:
234,818,143 ÷ 2 = 117,409,071.5
If the quotient is a whole number, then 2 and 117,409,071.5 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 | 234,818,143 | |
| -1 | -234,818,143 |
Now, we try dividing 234,818,143 by 3:
234,818,143 ÷ 3 = 78,272,714.3333
If the quotient is a whole number, then 3 and 78,272,714.3333 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 | 234,818,143 | |
| -1 | -234,818,143 |
Let's try dividing by 4:
234,818,143 ÷ 4 = 58,704,535.75
If the quotient is a whole number, then 4 and 58,704,535.75 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 | 234,818,143 | |
| -1 | 234,818,143 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 53 | 343 | 371 | 2,597 | 12,917 | 18,179 | 90,419 | 632,933 | 684,601 | 4,430,531 | 4,792,207 | 33,545,449 | 234,818,143 |
| -1 | -7 | -49 | -53 | -343 | -371 | -2,597 | -12,917 | -18,179 | -90,419 | -632,933 | -684,601 | -4,430,531 | -4,792,207 | -33,545,449 | -234,818,143 |
