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 244,452,515, 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 | 244,452,515 | |
| -1 | -244,452,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 244,452,515.
Example:
1 x 244,452,515 = 244,452,515
and
-1 x -244,452,515 = 244,452,515
Notice both answers equal 244,452,515
With that explanation out of the way, let's continue. Next, we take the number 244,452,515 and divide it by 2:
244,452,515 ÷ 2 = 122,226,257.5
If the quotient is a whole number, then 2 and 122,226,257.5 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 | 244,452,515 | |
| -1 | -244,452,515 |
Now, we try dividing 244,452,515 by 3:
244,452,515 ÷ 3 = 81,484,171.6667
If the quotient is a whole number, then 3 and 81,484,171.6667 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 | 244,452,515 | |
| -1 | -244,452,515 |
Let's try dividing by 4:
244,452,515 ÷ 4 = 61,113,128.75
If the quotient is a whole number, then 4 and 61,113,128.75 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 | 244,452,515 | |
| -1 | 244,452,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 67 | 155 | 335 | 2,077 | 10,385 | 23,539 | 117,695 | 729,709 | 1,577,113 | 3,648,545 | 7,885,565 | 48,890,503 | 244,452,515 |
| -1 | -5 | -31 | -67 | -155 | -335 | -2,077 | -10,385 | -23,539 | -117,695 | -729,709 | -1,577,113 | -3,648,545 | -7,885,565 | -48,890,503 | -244,452,515 |
