Question

Using division method find the HCF of 248 and 492.
​

Answer 1

Answer:We have to find the HCF of 248 and 492. Let us use the prime factorization method. Firstly, we have to write each number as a product of its prime factors. Let us consider 248. We can write 248 in its prime factorization form as

248=23×31

Now let us consider 492.

492=22×3×41

Now, we have to list the common factors of both the numbers.

Common factors of 248 and 492 are 22 .

The product of all common prime factors is the HCF. We have to use the lower power of each common factor.

Therefore, HCF of 248 and 492 is 22=2×2=4
