How do you find the HCF of a Class 3?

Steps to find the HCF of any given numbers;

  1. Larger number/ Smaller Number.
  2. The divisor of the above step / Remainder.
  3. The divisor of step 2 / remainder. Keep doing this step till R = 0(Zero).
  4. The last step’s divisor will be HCF.

How do you solve a HCF question?

How to find HCF by Prime Factorization?

  1. Step 1: Find the prime factors of the given numbers. In this case, the prime factors of 24 = 2 × 2 × 2 × 3, the prime factors of 36 = 2 × 2 × 3 × 3.
  2. Step 2: Multiply the prime factors that are common to both the numbers.
  3. Step 3: Therefore, the HCF of 24 and 36 is 12.

What is the HCF of 24 and 36?

12
Thus the HCF of 24 and 36 is 12.

How do you solve the HCF step by step?

Step 1: Divide the largest number by the smallest number. Step 2: Take divisor as new dividend and remainder as the new divisor, i.e. divide the first divisor by the first remainder. Step 3: Proceed till the remainder is zero and the last divisor will be the HCF of the given numbers. Therefore, HCF of 24 and 15 is 3.

How do you find the HCF in maths?

The highest common factor is found by multiplying all the factors which appear in both lists: So the HCF of 60 and 72 is 2 × 2 × 3 which is 12. The lowest common multiple is found by multiplying all the factors which appear in either list: So the LCM of 60 and 72 is 2 × 2 × 2 × 3 × 3 × 5 which is 360.

What is the easiest way to find HCF?

Step I: Treat the smallest number i.e., 12 as divisor and the bigger number i.e., 18 as dividend. Step II: The remainder 6 becomes the divisor and the divisor 12 becomes the dividend. Step III: Repeat this process till the remainder becomes zero. The last divisor is the H.C.F.

How do we find HCF of?

What is HCF in maths with examples?

HCF : The largest number that divides two or more numbers is the highest common factor (HCF) for those numbers. For example, consider the numbers 30 (2 x 3 x 5), 36 (2 x 2 x 3 x 3), 42 (2 x 3 x 7), 45 (3 x 3 x 5). 3 is the largest number that divides each of these numbers, and hence, is the HCF for these numbers.

How do you find the HCF example?

How do you find the HCF and LCM quickly?

The formula that shows the relationship between their LCM and HCF is: LCM (a,b) × HCF (a,b) = a × b. For example, let us take two numbers 12 and 8. Let us use the formula: LCM (12,8) × HCF (12,8) = 12 × 8. The LCM of 12 and 8 is 24; and the HCF of 12 and 8 is 4.
