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 147,001,463, 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 | 147,001,463 | |
| -1 | -147,001,463 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 147,001,463.
Example:
1 x 147,001,463 = 147,001,463
and
-1 x -147,001,463 = 147,001,463
Notice both answers equal 147,001,463
With that explanation out of the way, let's continue. Next, we take the number 147,001,463 and divide it by 2:
147,001,463 ÷ 2 = 73,500,731.5
If the quotient is a whole number, then 2 and 73,500,731.5 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 | 147,001,463 | |
| -1 | -147,001,463 |
Now, we try dividing 147,001,463 by 3:
147,001,463 ÷ 3 = 49,000,487.6667
If the quotient is a whole number, then 3 and 49,000,487.6667 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 | 147,001,463 | |
| -1 | -147,001,463 |
Let's try dividing by 4:
147,001,463 ÷ 4 = 36,750,365.75
If the quotient is a whole number, then 4 and 36,750,365.75 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 | 147,001,463 | |
| -1 | 147,001,463 |
If you did it right, you will end up with this table:
| 1 | 7 | 97 | 149 | 679 | 1,043 | 1,453 | 10,171 | 14,453 | 101,171 | 140,941 | 216,497 | 986,587 | 1,515,479 | 21,000,209 | 147,001,463 |
| -1 | -7 | -97 | -149 | -679 | -1,043 | -1,453 | -10,171 | -14,453 | -101,171 | -140,941 | -216,497 | -986,587 | -1,515,479 | -21,000,209 | -147,001,463 |
