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 146,263,523, 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 | 146,263,523 | |
| -1 | -146,263,523 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 146,263,523.
Example:
1 x 146,263,523 = 146,263,523
and
-1 x -146,263,523 = 146,263,523
Notice both answers equal 146,263,523
With that explanation out of the way, let's continue. Next, we take the number 146,263,523 and divide it by 2:
146,263,523 ÷ 2 = 73,131,761.5
If the quotient is a whole number, then 2 and 73,131,761.5 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 | 146,263,523 | |
| -1 | -146,263,523 |
Now, we try dividing 146,263,523 by 3:
146,263,523 ÷ 3 = 48,754,507.6667
If the quotient is a whole number, then 3 and 48,754,507.6667 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 | 146,263,523 | |
| -1 | -146,263,523 |
Let's try dividing by 4:
146,263,523 ÷ 4 = 36,565,880.75
If the quotient is a whole number, then 4 and 36,565,880.75 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 | 146,263,523 | |
| -1 | 146,263,523 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 79 | 287 | 553 | 3,239 | 6,451 | 22,673 | 45,157 | 264,491 | 509,629 | 1,851,437 | 3,567,403 | 20,894,789 | 146,263,523 |
| -1 | -7 | -41 | -79 | -287 | -553 | -3,239 | -6,451 | -22,673 | -45,157 | -264,491 | -509,629 | -1,851,437 | -3,567,403 | -20,894,789 | -146,263,523 |
