What number is HCF of 6?

Highest Common Factor

  • For Example:
  • Factors of 6 = 1, 2, 3 and 6.
  • Factors of 9 = 1, 3 and 9.
  • Therefore, common factor of 6 and 9 = 1 and 3.
  • Highest common factor (H.C.F) of 6 and 9 = 3.
  • Therefore, 3 is H.C.F. or G.C.D.
  • H.C.F.
  • Factors of 18 = 1, 2, 3, 6, 9 and 18.

What are the numbers known as whose HCF is 1?

Answer: If the HCF of two numbers is 1, the numbers are called co-prime numbers.

What 2 numbers have the HCF of 6?

Since their HCF is 6, let the numbers be 6m and 6n. Out of which only the pair (3,4) is coprime. Hence, the numbers are : 18 and 24.

What are the numbers whose LCM and HCF are equal?

solution: HCF and LCM of two numbers can be same only if two numbers are equal. Hence their difference will be zero.

What is the HCF of 6 and 8?

The HCF of 6 and 8 is 2. To calculate the Highest common factor of 6 and 8, we need to factor each number (factors of 6 = 1, 2, 3, 6; factors of 8 = 1, 2, 4, 8) and choose the highest factor that exactly divides both 6 and 8, i.e., 2.

How do you calculate HCF and LCM?

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.

How do you find LCM and HCF?

What is the relationship between LCM and HCF?

LCM and HCF have an interesting correlation between them. Some of LCM and HCF relations are as follows: Relation 1: The product of LCM and HCF of any two given numbers is equivalent to the product of the given numbers. Suppose P and Q are two numbers, then. Relation 2: As HCF of co-prime numbers is 1.

What is LCM of 6 8 and 12?

For example, LCM of 6, 8, and 12 is 24. Highest Common Factor (HCF): The greatest factor which is common to any two or more given natural numbers is termed as HCF of given numbers. Also known as GCD (Greatest Common Divisor). For example, HCF of 8,and 40 is 8.

What is the meaning of LCM in math?

Definition of LCM and HCF Lowest Common Multiple (LCM): The smallest number (other than zero) that is the common multiple of any two or more given natural numbers are termed as LCM. For example, LCM of 6, 8, and 12 is 24.

What is the HCF and lcm of 25 35 and 45?

From the above expression, we can say 5 is the only common factor for all the three numbers. Therefore, 5 is the HCF of 25, 35 and 45. Example: Find the Least Common Multiple of 36 and 44. Solution: Given, two numbers 36 and 44. Let us find out the LCM, by division method.
