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 354,622,765, 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 | 354,622,765 | |
| -1 | -354,622,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 354,622,765.
Example:
1 x 354,622,765 = 354,622,765
and
-1 x -354,622,765 = 354,622,765
Notice both answers equal 354,622,765
With that explanation out of the way, let's continue. Next, we take the number 354,622,765 and divide it by 2:
354,622,765 ÷ 2 = 177,311,382.5
If the quotient is a whole number, then 2 and 177,311,382.5 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 | 354,622,765 | |
| -1 | -354,622,765 |
Now, we try dividing 354,622,765 by 3:
354,622,765 ÷ 3 = 118,207,588.3333
If the quotient is a whole number, then 3 and 118,207,588.3333 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 | 354,622,765 | |
| -1 | -354,622,765 |
Let's try dividing by 4:
354,622,765 ÷ 4 = 88,655,691.25
If the quotient is a whole number, then 4 and 88,655,691.25 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 | 354,622,765 | |
| -1 | 354,622,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 523 | 2,615 | 3,661 | 18,305 | 19,373 | 96,865 | 135,611 | 678,055 | 10,132,079 | 50,660,395 | 70,924,553 | 354,622,765 |
| -1 | -5 | -7 | -35 | -523 | -2,615 | -3,661 | -18,305 | -19,373 | -96,865 | -135,611 | -678,055 | -10,132,079 | -50,660,395 | -70,924,553 | -354,622,765 |
