What is the HCF of 5 10 15 and 20?

The HCF of 5, 15 and 20 is 5. To calculate the highest common factor of 5, 15 and 20, we need to factor each number (factors of 5 = 1, 5; factors of 15 = 1, 3, 5, 15; factors of 20 = 1, 2, 4, 5, 10, 20) and choose the highest factor that exactly divides 5, 15 and 20, i.e., 5.

What is the HCF of 25?

To find the HCF of 25 and 40, we will find the prime factorization of the given numbers, i.e. 25 = 5 × 5; 40 = 2 × 2 × 2 × 5. ⇒ Since 5 is the only common prime factor of 25 and 40. Hence, HCF (25, 40) = 5.
