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 551,464,051, 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 | 551,464,051 | |
-1 | -551,464,051 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 551,464,051.
Example:
1 x 551,464,051 = 551,464,051
and
-1 x -551,464,051 = 551,464,051
Notice both answers equal 551,464,051
With that explanation out of the way, let's continue. Next, we take the number 551,464,051 and divide it by 2:
551,464,051 ÷ 2 = 275,732,025.5
If the quotient is a whole number, then 2 and 275,732,025.5 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 | 551,464,051 | |
-1 | -551,464,051 |
Now, we try dividing 551,464,051 by 3:
551,464,051 ÷ 3 = 183,821,350.3333
If the quotient is a whole number, then 3 and 183,821,350.3333 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 | 551,464,051 | |
-1 | -551,464,051 |
Let's try dividing by 4:
551,464,051 ÷ 4 = 137,866,012.75
If the quotient is a whole number, then 4 and 137,866,012.75 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 | 551,464,051 | |
-1 | 551,464,051 |
If you did it right, you will end up with this table:
1 | 10,111 | 54,541 | 551,464,051 |
-1 | -10,111 | -54,541 | -551,464,051 |
