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 145,597,435, 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 | 145,597,435 | |
| -1 | -145,597,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,597,435.
Example:
1 x 145,597,435 = 145,597,435
and
-1 x -145,597,435 = 145,597,435
Notice both answers equal 145,597,435
With that explanation out of the way, let's continue. Next, we take the number 145,597,435 and divide it by 2:
145,597,435 ÷ 2 = 72,798,717.5
If the quotient is a whole number, then 2 and 72,798,717.5 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 | 145,597,435 | |
| -1 | -145,597,435 |
Now, we try dividing 145,597,435 by 3:
145,597,435 ÷ 3 = 48,532,478.3333
If the quotient is a whole number, then 3 and 48,532,478.3333 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 | 145,597,435 | |
| -1 | -145,597,435 |
Let's try dividing by 4:
145,597,435 ÷ 4 = 36,399,358.75
If the quotient is a whole number, then 4 and 36,399,358.75 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 | 145,597,435 | |
| -1 | 145,597,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 137 | 685 | 2,329 | 11,645 | 12,503 | 62,515 | 212,551 | 1,062,755 | 1,712,911 | 8,564,555 | 29,119,487 | 145,597,435 |
| -1 | -5 | -17 | -85 | -137 | -685 | -2,329 | -11,645 | -12,503 | -62,515 | -212,551 | -1,062,755 | -1,712,911 | -8,564,555 | -29,119,487 | -145,597,435 |
