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 45,571,141, 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 | 45,571,141 | |
| -1 | -45,571,141 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,571,141.
Example:
1 x 45,571,141 = 45,571,141
and
-1 x -45,571,141 = 45,571,141
Notice both answers equal 45,571,141
With that explanation out of the way, let's continue. Next, we take the number 45,571,141 and divide it by 2:
45,571,141 ÷ 2 = 22,785,570.5
If the quotient is a whole number, then 2 and 22,785,570.5 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 | 45,571,141 | |
| -1 | -45,571,141 |
Now, we try dividing 45,571,141 by 3:
45,571,141 ÷ 3 = 15,190,380.3333
If the quotient is a whole number, then 3 and 15,190,380.3333 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 | 45,571,141 | |
| -1 | -45,571,141 |
Let's try dividing by 4:
45,571,141 ÷ 4 = 11,392,785.25
If the quotient is a whole number, then 4 and 11,392,785.25 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 | 45,571,141 | |
| -1 | 45,571,141 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 121 | 173 | 311 | 847 | 1,211 | 1,903 | 2,177 | 3,421 | 13,321 | 20,933 | 23,947 | 37,631 | 53,803 | 146,531 | 263,417 | 376,621 | 591,833 | 4,142,831 | 6,510,163 | 45,571,141 |
| -1 | -7 | -11 | -77 | -121 | -173 | -311 | -847 | -1,211 | -1,903 | -2,177 | -3,421 | -13,321 | -20,933 | -23,947 | -37,631 | -53,803 | -146,531 | -263,417 | -376,621 | -591,833 | -4,142,831 | -6,510,163 | -45,571,141 |
