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 72,652,451, 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 | 72,652,451 | |
-1 | -72,652,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 72,652,451.
Example:
1 x 72,652,451 = 72,652,451
and
-1 x -72,652,451 = 72,652,451
Notice both answers equal 72,652,451
With that explanation out of the way, let's continue. Next, we take the number 72,652,451 and divide it by 2:
72,652,451 ÷ 2 = 36,326,225.5
If the quotient is a whole number, then 2 and 36,326,225.5 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 | 72,652,451 | |
-1 | -72,652,451 |
Now, we try dividing 72,652,451 by 3:
72,652,451 ÷ 3 = 24,217,483.6667
If the quotient is a whole number, then 3 and 24,217,483.6667 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 | 72,652,451 | |
-1 | -72,652,451 |
Let's try dividing by 4:
72,652,451 ÷ 4 = 18,163,112.75
If the quotient is a whole number, then 4 and 18,163,112.75 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 | 72,652,451 | |
-1 | 72,652,451 |
If you did it right, you will end up with this table:
1 | 41 | 1,772,011 | 72,652,451 |
-1 | -41 | -1,772,011 | -72,652,451 |
