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 146,410,447, 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 | 146,410,447 | |
| -1 | -146,410,447 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 146,410,447.
Example:
1 x 146,410,447 = 146,410,447
and
-1 x -146,410,447 = 146,410,447
Notice both answers equal 146,410,447
With that explanation out of the way, let's continue. Next, we take the number 146,410,447 and divide it by 2:
146,410,447 ÷ 2 = 73,205,223.5
If the quotient is a whole number, then 2 and 73,205,223.5 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 | 146,410,447 | |
| -1 | -146,410,447 |
Now, we try dividing 146,410,447 by 3:
146,410,447 ÷ 3 = 48,803,482.3333
If the quotient is a whole number, then 3 and 48,803,482.3333 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 | 146,410,447 | |
| -1 | -146,410,447 |
Let's try dividing by 4:
146,410,447 ÷ 4 = 36,602,611.75
If the quotient is a whole number, then 4 and 36,602,611.75 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 | 146,410,447 | |
| -1 | 146,410,447 |
If you did it right, you will end up with this table:
| 1 | 19 | 59 | 131 | 997 | 1,121 | 2,489 | 7,729 | 18,943 | 58,823 | 130,607 | 146,851 | 1,117,637 | 2,481,533 | 7,705,813 | 146,410,447 |
| -1 | -19 | -59 | -131 | -997 | -1,121 | -2,489 | -7,729 | -18,943 | -58,823 | -130,607 | -146,851 | -1,117,637 | -2,481,533 | -7,705,813 | -146,410,447 |
