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 145,654,855, 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 | 145,654,855 | |
| -1 | -145,654,855 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,654,855.
Example:
1 x 145,654,855 = 145,654,855
and
-1 x -145,654,855 = 145,654,855
Notice both answers equal 145,654,855
With that explanation out of the way, let's continue. Next, we take the number 145,654,855 and divide it by 2:
145,654,855 ÷ 2 = 72,827,427.5
If the quotient is a whole number, then 2 and 72,827,427.5 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 | 145,654,855 | |
| -1 | -145,654,855 |
Now, we try dividing 145,654,855 by 3:
145,654,855 ÷ 3 = 48,551,618.3333
If the quotient is a whole number, then 3 and 48,551,618.3333 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 | 145,654,855 | |
| -1 | -145,654,855 |
Let's try dividing by 4:
145,654,855 ÷ 4 = 36,413,713.75
If the quotient is a whole number, then 4 and 36,413,713.75 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 | 145,654,855 | |
| -1 | 145,654,855 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 971 | 1,579 | 4,855 | 7,895 | 18,449 | 30,001 | 92,245 | 150,005 | 1,533,209 | 7,666,045 | 29,130,971 | 145,654,855 |
| -1 | -5 | -19 | -95 | -971 | -1,579 | -4,855 | -7,895 | -18,449 | -30,001 | -92,245 | -150,005 | -1,533,209 | -7,666,045 | -29,130,971 | -145,654,855 |
