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 351,020,527, 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 | 351,020,527 | |
| -1 | -351,020,527 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 351,020,527.
Example:
1 x 351,020,527 = 351,020,527
and
-1 x -351,020,527 = 351,020,527
Notice both answers equal 351,020,527
With that explanation out of the way, let's continue. Next, we take the number 351,020,527 and divide it by 2:
351,020,527 ÷ 2 = 175,510,263.5
If the quotient is a whole number, then 2 and 175,510,263.5 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 | 351,020,527 | |
| -1 | -351,020,527 |
Now, we try dividing 351,020,527 by 3:
351,020,527 ÷ 3 = 117,006,842.3333
If the quotient is a whole number, then 3 and 117,006,842.3333 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 | 351,020,527 | |
| -1 | -351,020,527 |
Let's try dividing by 4:
351,020,527 ÷ 4 = 87,755,131.75
If the quotient is a whole number, then 4 and 87,755,131.75 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 | 351,020,527 | |
| -1 | 351,020,527 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 1,217 | 2,017 | 13,387 | 15,821 | 22,187 | 26,221 | 174,031 | 288,431 | 2,454,689 | 27,001,579 | 31,910,957 | 351,020,527 |
| -1 | -11 | -13 | -143 | -1,217 | -2,017 | -13,387 | -15,821 | -22,187 | -26,221 | -174,031 | -288,431 | -2,454,689 | -27,001,579 | -31,910,957 | -351,020,527 |
