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 45,016,153, 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 | 45,016,153 | |
| -1 | -45,016,153 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,016,153.
Example:
1 x 45,016,153 = 45,016,153
and
-1 x -45,016,153 = 45,016,153
Notice both answers equal 45,016,153
With that explanation out of the way, let's continue. Next, we take the number 45,016,153 and divide it by 2:
45,016,153 ÷ 2 = 22,508,076.5
If the quotient is a whole number, then 2 and 22,508,076.5 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 | 45,016,153 | |
| -1 | -45,016,153 |
Now, we try dividing 45,016,153 by 3:
45,016,153 ÷ 3 = 15,005,384.3333
If the quotient is a whole number, then 3 and 15,005,384.3333 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 | 45,016,153 | |
| -1 | -45,016,153 |
Let's try dividing by 4:
45,016,153 ÷ 4 = 11,254,038.25
If the quotient is a whole number, then 4 and 11,254,038.25 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 | 45,016,153 | |
| -1 | 45,016,153 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 17 | 49 | 91 | 119 | 221 | 637 | 833 | 1,547 | 4,157 | 10,829 | 29,099 | 54,041 | 70,669 | 203,693 | 378,287 | 494,683 | 918,697 | 2,648,009 | 3,462,781 | 6,430,879 | 45,016,153 |
| -1 | -7 | -13 | -17 | -49 | -91 | -119 | -221 | -637 | -833 | -1,547 | -4,157 | -10,829 | -29,099 | -54,041 | -70,669 | -203,693 | -378,287 | -494,683 | -918,697 | -2,648,009 | -3,462,781 | -6,430,879 | -45,016,153 |
