Find the prime factorization of 221

Prime factorisation is a method to find the prime factors of a given number, say a composite number. These factors are nothing but the prime numbers. A prime number is a number which has only two factors, i.e. 1 and the number itself.

Prime factorisation of 221

Here we have to find the prime factors of 221.

Divide 221 by 3;

221 ÷ 13 = 17

Divide 17 by 17

17 ÷ 17 = 1

Now, we have got the quotient as 1. So no further division is possible.

Therefore, the prime factorisation of 221 is 13 X 17

Answer

Prime factorization of 221 = 13 X 17
