Is a factor of B then HCF of A and B is?

a is divisible by b because b is a factor of a……. so HCF will be b because we know that hcf is lowest and common….

What is a is a factor of B?

a is factor of 2b. so 2b/a = an integer. which means “a” has to be a multiple of 2. so if b is 3 or any other prime a cannot be a factor of b, but otherwise, a can be a factor of b.

What is the HCF of 2 and?

HCF or highest common factor is the factor of any two or more numbers, which are common among them. Sometimes, it is also called the greatest common factor (GCF) or greatest common divisor (GCD). For example, the HCF of 2 and 4 is 2, because 2 is the number which is common to both 2 and 4.

What is HCF of A and B?

We say that d is the highest common factor of a and b if there is no other factor of both a and b that is greater than d. Notation: HCF(a,b) = “highest common factor of a and b” . This is also sometimes denoted by GCD(a,b) read as “the greatest common divisor of a and b”.

What is the LCM of A and B if A is factor of B?

Answer: Step-by-step explanation: there lcm would be b.

What is the HCF of 3 and 5?

1
Answer: HCF of 3 and 5 is 1.

What is the HCF of 10?

Factors of 10 = 1, 2, 5 and 10. Therefore, common factor of 15 and 10 = 1 and 5. Highest common factor (H.C.F) of 15 and 10 = 5.

How do you find the HCF of 2 and 4?

To find the HCF of 2 and 4, we will find the prime factorization of the given numbers, i.e. 2 = 2; 4 = 2 × 2. ⇒ Since 2 is the only common prime factor of 2 and 4. Hence, HCF (2, 4) = 2. ☛ What is a Prime Number?

What is the LCM of A and B?

For two integers a and b, denoted LCM(a,b), the LCM is the smallest positive integer that is evenly divisible by both a and b. For example, LCM(2,3) = 6 and LCM(6,10) = 30.

What is the LCM of two prime numbers A and B?

Solution: LCM of two prime numbers is always the product of these two numbers as their common factor is only 1.

What is the HCF of A and B?

The HCF and A and B will be A. A is a factor of itself, and it is a factor of B. Since A cannot have a factor greater than itself, it is the HCF. The HCF between them is 5. The HCF of A and B is 15. How do I get rid of grey hair naturally without dye?

How do you find the HCF of a set of numbers?

Let us understand how to find out HCF using this method: 1 Write each number as a product of its prime factors. 2 Now list the common factors of both numbers. 3 The product of all common prime factors is the HCF (use the lower power of each common factor).

What is the LCM and HCF of two prime numbers?

The LCM of given numbers is never less than any of the numbers. The HCF of two or more prime numbers is always 1. The LCM of two or more prime numbers is nothing but their product. The product of two numbers, a and b, is equal to the product of their HCF and LCM.

What is hcf (greatest common factor)?

The greatest common factor (GCF or GCD or HCF) of a set of whole numbers is the largest positive integer that divides evenly all the given numbers with zero remainders. HCF stands for Highest Common Factor. HCF is also known as GCF (Greatest Common Factor) or GCD (Greatest Common Divisor).
