List all the factors of 12.
Number | Factors |
12 | 1 , 2 , 3 , 4 , 6 , 12 |
Use only prime factors of 12 and do the downward division or upside-down division to divide 12 as follows;
Now write the multiplication with the product of 12.
The answer can also be written with an exponent which is the shorthand for repeated multiplication.
* 2 is repeated twice in the above multiplication. So we also can write the answer as follows;
Prime factorisation of 12 is;
