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 135,478,261, 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 | 135,478,261 | |
-1 | -135,478,261 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 135,478,261.
Example:
1 x 135,478,261 = 135,478,261
and
-1 x -135,478,261 = 135,478,261
Notice both answers equal 135,478,261
With that explanation out of the way, let's continue. Next, we take the number 135,478,261 and divide it by 2:
135,478,261 ÷ 2 = 67,739,130.5
If the quotient is a whole number, then 2 and 67,739,130.5 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 | 135,478,261 | |
-1 | -135,478,261 |
Now, we try dividing 135,478,261 by 3:
135,478,261 ÷ 3 = 45,159,420.3333
If the quotient is a whole number, then 3 and 45,159,420.3333 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 | 135,478,261 | |
-1 | -135,478,261 |
Let's try dividing by 4:
135,478,261 ÷ 4 = 33,869,565.25
If the quotient is a whole number, then 4 and 33,869,565.25 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 | 135,478,261 | |
-1 | 135,478,261 |
If you did it right, you will end up with this table:
1 | 3,319 | 40,819 | 135,478,261 |
-1 | -3,319 | -40,819 | -135,478,261 |
