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 145,424,405, 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 | 145,424,405 | |
| -1 | -145,424,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,424,405.
Example:
1 x 145,424,405 = 145,424,405
and
-1 x -145,424,405 = 145,424,405
Notice both answers equal 145,424,405
With that explanation out of the way, let's continue. Next, we take the number 145,424,405 and divide it by 2:
145,424,405 ÷ 2 = 72,712,202.5
If the quotient is a whole number, then 2 and 72,712,202.5 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 | 145,424,405 | |
| -1 | -145,424,405 |
Now, we try dividing 145,424,405 by 3:
145,424,405 ÷ 3 = 48,474,801.6667
If the quotient is a whole number, then 3 and 48,474,801.6667 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 | 145,424,405 | |
| -1 | -145,424,405 |
Let's try dividing by 4:
145,424,405 ÷ 4 = 36,356,101.25
If the quotient is a whole number, then 4 and 36,356,101.25 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 | 145,424,405 | |
| -1 | 145,424,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 691 | 859 | 3,455 | 4,295 | 4,837 | 6,013 | 24,185 | 30,065 | 33,859 | 42,091 | 169,295 | 210,455 | 593,569 | 2,967,845 | 4,154,983 | 20,774,915 | 29,084,881 | 145,424,405 |
| -1 | -5 | -7 | -35 | -49 | -245 | -691 | -859 | -3,455 | -4,295 | -4,837 | -6,013 | -24,185 | -30,065 | -33,859 | -42,091 | -169,295 | -210,455 | -593,569 | -2,967,845 | -4,154,983 | -20,774,915 | -29,084,881 | -145,424,405 |
