What is the HCF of XY X and Y?

So, H.C.F of (x-y, x+y) =1. Therefore, H.C.F of (x-y, x+y) is 1 or 2.

What is the HCF of two numbers X and Y?

HCF will always be 1. As Prime Numbers have 1 and the number itself as a common factor. Now, For any Non-Prime Number, X and Y, then none of the give option is correct.

How do you find the HCF of a literal coefficient?

To find the highest common factor (H.C.F.) or greatest common factor (G.C.F.) of two or more monomials is the product of the H.C.F. of their numerical coefficients and the H.C.F. of their literal coefficients. Note: Note: The H.C.F. of literal coefficients is each common literal with the lowest power.

How do you find the HCF of a quadratic equation?

How to find the Highest Common Factor of Polynomials by Division Method?

1. Let us take two polynomials f(x), g(x).
2. Divide the polynomials f(x) / g(x) to get f(x) = g(x) * q(x) + r(x).
3. If the remainder r(x) is zer0, then g(x) is the highest common factor of polynomials.

How do you find the HCF of an algebraic expression?

Finding H.C.F Using Prime Factorisation Method

1. Write each of the algebraic expressions as a product of its prime factors.
2. Then you have to make a list of the common factors for the algebraic expressions.
3. The product of the prime factors is considered as H.C.F.

How do you find the HCF of an equation?

What is the HCF of 4ab and 6bc?

Therefore, our required HCF is 2b.

What is the HCF of 2x3x5?

2 2 x 3 x 5 = 60. 3 x 5 2 = 75. The product of all common prime factors is the HCF. The common prime factors in this example are 3 & 5. The lowest power of 3 is 3 and 5 is 5. So, HCF = 3 x 5 = 15

What is the meaning of HCF in math?

HCF – Highest Common Factor The greatest number which divides each of the two or more numbers is called HCF or Highest Common Factor. It is also called the Greatest Common Measure (GCM) and Greatest Common Divisor (GCD).

How to find the HCF of more than 3 numbers?

1) Calculate the HCF of 2 numbers. 2) Then Find the HCF of 3rd number and the HCF found in step 1. 3) The HCF you got in step 2 will be the HCF of the 3 numbers. The above steps can also be used to find the HCF of more than 3 numbers. Here is a few more example to find the highest common factors. Example 1: Find out HCF of 30 and 45.

How to solve problems of HCF?

Follow the steps mentioned below to solve problems of hcf. Step 1: Write the given numbers horizontally, in a sequence, by separating it with commas. Step 2: Find the smallest prime number which can divide the given number. It should exactly divide the given numbers. (Write on the left side).
