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 147,299,299, 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 | 147,299,299 | |
| -1 | -147,299,299 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 147,299,299.
Example:
1 x 147,299,299 = 147,299,299
and
-1 x -147,299,299 = 147,299,299
Notice both answers equal 147,299,299
With that explanation out of the way, let's continue. Next, we take the number 147,299,299 and divide it by 2:
147,299,299 ÷ 2 = 73,649,649.5
If the quotient is a whole number, then 2 and 73,649,649.5 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 | 147,299,299 | |
| -1 | -147,299,299 |
Now, we try dividing 147,299,299 by 3:
147,299,299 ÷ 3 = 49,099,766.3333
If the quotient is a whole number, then 3 and 49,099,766.3333 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 | 147,299,299 | |
| -1 | -147,299,299 |
Let's try dividing by 4:
147,299,299 ÷ 4 = 36,824,824.75
If the quotient is a whole number, then 4 and 36,824,824.75 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 | 147,299,299 | |
| -1 | 147,299,299 |
If you did it right, you will end up with this table:
| 1 | 7 | 67 | 127 | 469 | 889 | 2,473 | 8,509 | 17,311 | 59,563 | 165,691 | 314,071 | 1,159,837 | 2,198,497 | 21,042,757 | 147,299,299 |
| -1 | -7 | -67 | -127 | -469 | -889 | -2,473 | -8,509 | -17,311 | -59,563 | -165,691 | -314,071 | -1,159,837 | -2,198,497 | -21,042,757 | -147,299,299 |
