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 354,510,299, 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 | 354,510,299 | |
| -1 | -354,510,299 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 354,510,299.
Example:
1 x 354,510,299 = 354,510,299
and
-1 x -354,510,299 = 354,510,299
Notice both answers equal 354,510,299
With that explanation out of the way, let's continue. Next, we take the number 354,510,299 and divide it by 2:
354,510,299 ÷ 2 = 177,255,149.5
If the quotient is a whole number, then 2 and 177,255,149.5 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 | 354,510,299 | |
| -1 | -354,510,299 |
Now, we try dividing 354,510,299 by 3:
354,510,299 ÷ 3 = 118,170,099.6667
If the quotient is a whole number, then 3 and 118,170,099.6667 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 | 354,510,299 | |
| -1 | -354,510,299 |
Let's try dividing by 4:
354,510,299 ÷ 4 = 88,627,574.75
If the quotient is a whole number, then 4 and 88,627,574.75 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 | 354,510,299 | |
| -1 | 354,510,299 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 17 | 143 | 187 | 221 | 2,431 | 145,829 | 1,604,119 | 1,895,777 | 2,479,093 | 20,853,547 | 27,270,023 | 32,228,209 | 354,510,299 |
| -1 | -11 | -13 | -17 | -143 | -187 | -221 | -2,431 | -145,829 | -1,604,119 | -1,895,777 | -2,479,093 | -20,853,547 | -27,270,023 | -32,228,209 | -354,510,299 |
