It is the multiplication of a number as the product of prime factors.
List all the factors of 12.
1 , 2 , 3 , 4 , 6 , 12
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;
