What is the HCF of 9 and 10?

1
The Greatest Common Factor of 9 and 10 is 1.

How do you find the LCM when given HCF?

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 the HCF of Class 9?

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.

Is HCF and LCM same?

LCM and HCF of two numbers are the same. HCF being the highest common factor is always a factor of both the numbers. Therefore the numbers can be written as multiples of HCF.

What is HCF of two numbers?

HCF (Highest Common Factor) or GCD (Greatest Common Divisor) of two numbers is the largest number that divides both of them.

How do you find the HCF of two numbers?

HCF of two numbers by Division Method

  1. First, divide the large number by a small number.
  2. If the remainder is left, then divide the first divisor by remainder.
  3. If the remainder divides the first divisor completely, then it is the HCF or highest common factor of the given two numbers.

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.

How to find the HCF of more than 3 numbers?

The above steps can also be used to find the HCF of more than 3 numbers. Example: Find the HCF of 144 and 160 by division method. Since 160>144, so the dividend will be 160 and the divisor will be 144. Hence, we can see here 16 is the highest number which divides 160 and 144. To calculate the LCM of two numbers 60 and 45.
