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 145,348,825, 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 | 145,348,825 | |
| -1 | -145,348,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,348,825.
Example:
1 x 145,348,825 = 145,348,825
and
-1 x -145,348,825 = 145,348,825
Notice both answers equal 145,348,825
With that explanation out of the way, let's continue. Next, we take the number 145,348,825 and divide it by 2:
145,348,825 ÷ 2 = 72,674,412.5
If the quotient is a whole number, then 2 and 72,674,412.5 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 | 145,348,825 | |
| -1 | -145,348,825 |
Now, we try dividing 145,348,825 by 3:
145,348,825 ÷ 3 = 48,449,608.3333
If the quotient is a whole number, then 3 and 48,449,608.3333 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 | 145,348,825 | |
| -1 | -145,348,825 |
Let's try dividing by 4:
145,348,825 ÷ 4 = 36,337,206.25
If the quotient is a whole number, then 4 and 36,337,206.25 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 | 145,348,825 | |
| -1 | 145,348,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 139 | 151 | 277 | 695 | 755 | 1,385 | 3,475 | 3,775 | 6,925 | 20,989 | 38,503 | 41,827 | 104,945 | 192,515 | 209,135 | 524,725 | 962,575 | 1,045,675 | 5,813,953 | 29,069,765 | 145,348,825 |
| -1 | -5 | -25 | -139 | -151 | -277 | -695 | -755 | -1,385 | -3,475 | -3,775 | -6,925 | -20,989 | -38,503 | -41,827 | -104,945 | -192,515 | -209,135 | -524,725 | -962,575 | -1,045,675 | -5,813,953 | -29,069,765 | -145,348,825 |
