Question

express 20 as a product of prime numbers​

Answer 1

Answer:

20 = 2 * 2 * 5

Step-by-step explanation:

Prime factorization of a number is breaking a number down into a set of prime numbers which multiply together to result in the original number.

We can prime factorise a number by repeatedly dividing it with the smallest prime number possible.

So,

20/2 = 10

10/2 = 5

5/5 = 1

Ans: Hence, the prime factorisation of 20 is 2 * 2 * 5.
