What is the HCF of even prime number?

Step-by-step explanation: ∴ H.C.F of the smallest prime number and the smallest composite number is 2.

What is HCF of even numbers?

The HCF of any two consecutive even numbers is always 2.

What is HCF of even number and odd number?

Example: HCF of 8 and 21 is 1. HCF of 6 and 9 is 3.

What is a prime number and an even number?

Even number: Any number that can be easily divided by 2 is called an even number. Prime numbers are numbers which have exactly two factors : 1 and themselves. For example the first 5 prime numbers are 2, 3, 5, 7 and 11. By contrast, numbers with more than two factors are called composite numbers.

What is the HCF of 2 and an even number?

HCF of 2 and even number will be 2 itself. It is because the highest common factor of the even number taken would be 2. 2 is also the highest factor of 2 only. 2 is the common factor between these 2 numbers.

What is the HCF of two odd number?

1
Consecutive odd numbers have no common factor. so their HCF is 1.

What is the HCF of two co prime number?

The HCF of two coprime numbers is always 1. For example, 5 and 9 are coprime numbers, there, HCF (5, 9) = 1. The LCM of two co-prime numbers is always their product.

What is the HCF of 144 and 180?

36
Hence, the HCF of 144 and 180 is 36.

How do you find the HCF of two prime numbers?

In order to find the HCF, the foolproof method is to split both numbers down into their prime factors, then keep the common ones. If one number (call it P) is prime, it doesn’t have any prime factors other than itself. Hence the HCF of P and any other number can only ever be P or 1.

What is the HCF of the smallest prime number and composite number?

Clearly, 2 is a factor of 4, so their H.C.F. is 2 . Thus, the H.C.F. of the smallest prime number and the smallest composite number is 2. Was this answer helpful?

What is the HCF (highest common factor)?

The HCF (Highest Common Factor) of two or more numbers is the highest number among all the common factors of the given numbers or in simple words, the HCF (Highest Common Factor) of two natural numbers x and y is the largest possible number that divides both x and y.

What is the HCF calculator?

Here is the interesting HCF calculator to find the highest common factor for the given list of numbers. Such factor is also referred to as the greatest common factor (GCF) or greatest common measure (GCM) or highest common divisor is the highest number which divides all the numbers in the list exactly.
