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 356,400,247, 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 | 356,400,247 | |
| -1 | -356,400,247 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 356,400,247.
Example:
1 x 356,400,247 = 356,400,247
and
-1 x -356,400,247 = 356,400,247
Notice both answers equal 356,400,247
With that explanation out of the way, let's continue. Next, we take the number 356,400,247 and divide it by 2:
356,400,247 ÷ 2 = 178,200,123.5
If the quotient is a whole number, then 2 and 178,200,123.5 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 | 356,400,247 | |
| -1 | -356,400,247 |
Now, we try dividing 356,400,247 by 3:
356,400,247 ÷ 3 = 118,800,082.3333
If the quotient is a whole number, then 3 and 118,800,082.3333 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 | 356,400,247 | |
| -1 | -356,400,247 |
Let's try dividing by 4:
356,400,247 ÷ 4 = 89,100,061.75
If the quotient is a whole number, then 4 and 89,100,061.75 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 | 356,400,247 | |
| -1 | 356,400,247 |
If you did it right, you will end up with this table:
| 1 | 7 | 61 | 317 | 427 | 2,219 | 2,633 | 18,431 | 19,337 | 135,359 | 160,613 | 834,661 | 1,124,291 | 5,842,627 | 50,914,321 | 356,400,247 |
| -1 | -7 | -61 | -317 | -427 | -2,219 | -2,633 | -18,431 | -19,337 | -135,359 | -160,613 | -834,661 | -1,124,291 | -5,842,627 | -50,914,321 | -356,400,247 |
