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 154,252,051, 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 | 154,252,051 | |
| -1 | -154,252,051 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 154,252,051.
Example:
1 x 154,252,051 = 154,252,051
and
-1 x -154,252,051 = 154,252,051
Notice both answers equal 154,252,051
With that explanation out of the way, let's continue. Next, we take the number 154,252,051 and divide it by 2:
154,252,051 ÷ 2 = 77,126,025.5
If the quotient is a whole number, then 2 and 77,126,025.5 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 | 154,252,051 | |
| -1 | -154,252,051 |
Now, we try dividing 154,252,051 by 3:
154,252,051 ÷ 3 = 51,417,350.3333
If the quotient is a whole number, then 3 and 51,417,350.3333 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 | 154,252,051 | |
| -1 | -154,252,051 |
Let's try dividing by 4:
154,252,051 ÷ 4 = 38,563,012.75
If the quotient is a whole number, then 4 and 38,563,012.75 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 | 154,252,051 | |
| -1 | 154,252,051 |
If you did it right, you will end up with this table:
| 1 | 19 | 43 | 361 | 523 | 817 | 6,859 | 9,937 | 15,523 | 22,489 | 188,803 | 294,937 | 427,291 | 3,587,257 | 8,118,529 | 154,252,051 |
| -1 | -19 | -43 | -361 | -523 | -817 | -6,859 | -9,937 | -15,523 | -22,489 | -188,803 | -294,937 | -427,291 | -3,587,257 | -8,118,529 | -154,252,051 |
