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 146,068,415, 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 | 146,068,415 | |
| -1 | -146,068,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 146,068,415.
Example:
1 x 146,068,415 = 146,068,415
and
-1 x -146,068,415 = 146,068,415
Notice both answers equal 146,068,415
With that explanation out of the way, let's continue. Next, we take the number 146,068,415 and divide it by 2:
146,068,415 ÷ 2 = 73,034,207.5
If the quotient is a whole number, then 2 and 73,034,207.5 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 | 146,068,415 | |
| -1 | -146,068,415 |
Now, we try dividing 146,068,415 by 3:
146,068,415 ÷ 3 = 48,689,471.6667
If the quotient is a whole number, then 3 and 48,689,471.6667 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 | 146,068,415 | |
| -1 | -146,068,415 |
Let's try dividing by 4:
146,068,415 ÷ 4 = 36,517,103.75
If the quotient is a whole number, then 4 and 36,517,103.75 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 | 146,068,415 | |
| -1 | 146,068,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 127 | 185 | 635 | 4,699 | 6,217 | 23,495 | 31,085 | 230,029 | 789,559 | 1,150,145 | 3,947,795 | 29,213,683 | 146,068,415 |
| -1 | -5 | -37 | -127 | -185 | -635 | -4,699 | -6,217 | -23,495 | -31,085 | -230,029 | -789,559 | -1,150,145 | -3,947,795 | -29,213,683 | -146,068,415 |
