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 56,949,649, 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 | 56,949,649 | |
-1 | -56,949,649 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 56,949,649.
Example:
1 x 56,949,649 = 56,949,649
and
-1 x -56,949,649 = 56,949,649
Notice both answers equal 56,949,649
With that explanation out of the way, let's continue. Next, we take the number 56,949,649 and divide it by 2:
56,949,649 ÷ 2 = 28,474,824.5
If the quotient is a whole number, then 2 and 28,474,824.5 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 | 56,949,649 | |
-1 | -56,949,649 |
Now, we try dividing 56,949,649 by 3:
56,949,649 ÷ 3 = 18,983,216.3333
If the quotient is a whole number, then 3 and 18,983,216.3333 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 | 56,949,649 | |
-1 | -56,949,649 |
Let's try dividing by 4:
56,949,649 ÷ 4 = 14,237,412.25
If the quotient is a whole number, then 4 and 14,237,412.25 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 | 56,949,649 | |
-1 | 56,949,649 |
If you did it right, you will end up with this table:
1 | 29 | 1,963,781 | 56,949,649 |
-1 | -29 | -1,963,781 | -56,949,649 |
