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 145,900,465, 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 | 145,900,465 | |
-1 | -145,900,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,900,465.
Example:
1 x 145,900,465 = 145,900,465
and
-1 x -145,900,465 = 145,900,465
Notice both answers equal 145,900,465
With that explanation out of the way, let's continue. Next, we take the number 145,900,465 and divide it by 2:
145,900,465 ÷ 2 = 72,950,232.5
If the quotient is a whole number, then 2 and 72,950,232.5 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 | 145,900,465 | |
-1 | -145,900,465 |
Now, we try dividing 145,900,465 by 3:
145,900,465 ÷ 3 = 48,633,488.3333
If the quotient is a whole number, then 3 and 48,633,488.3333 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 | 145,900,465 | |
-1 | -145,900,465 |
Let's try dividing by 4:
145,900,465 ÷ 4 = 36,475,116.25
If the quotient is a whole number, then 4 and 36,475,116.25 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 | 145,900,465 | |
-1 | 145,900,465 |
If you did it right, you will end up with this table:
1 | 5 | 29,180,093 | 145,900,465 |
-1 | -5 | -29,180,093 | -145,900,465 |
