What is the sum of LCM and HCF?

The sum of LCM and HCF is 600. If one number is 280, then the other number is

What is the HCF of two numbers?

[Solved] The HCF of two numbers is 24. If sum of the numbers is 480, Given: HCF = 24 Sum of two number = 480 Concept used: If the number is 24a and 24b, then a and b will be prime number Calculation: Let the number be 24a a

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 calculate the LCM of two numbers 60 and 45?

To calculate the LCM of two numbers 60 and 45. Out of other ways, One way to find the LCM of given numbers is as below: List the prime factors of each number first. Then multiply each factor the most number of times it occurs in any number.

How to find the LCM of two numbers?

The LCM of two numbers is 45 times their HCF . If one of the numbers is 225 and sum of their LCM and HCF is 1150, find the the other number. Was this answer helpful? If HCF of a and b is 12 and the product of this number is 1800, find LCM of a and b.

What is the LCM of 280 and 80?

If one number is 280, then the other number is The LCM of two numbers is 14 times their HCF. The sum of LCM and HCF is 600. If one number is 280, then the other number is hence the other number is 80. Was this answer helpful?

What is the least common multiple of two numbers?

The smallest positive number that is a multiple of two or more numbers is known as the LCM or least common multiple Answer: If the LCM of two numbers is 14 times their HCF and the sum of LCM and HCF is 600, one number being 280, the other number is 80

Note: HCF of Sum & LCM is also same as actual HCF of two numbers. Factorize both 132 and 216 and find the HCF. Question 4: The LCM of two numbers is 15 times of HCF. The sum of HCF and LCM is 480.

What is the difference between the LCM and HCF of the numbers 20 30 and 40?

Now, the LCM (Least common multiple) in the above three equations are given by the common factor along with other factors. Similarly, the HCF (Highest common factor) in the above three equations is $ = 2 \times 5 = 10$. Therefore, the required answer – LCM and HCF of $20,30$ and $40$ are $120$ and $10$.

How do you solve the 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.

How do you find the HCF and LCM ratio?

Answer

1. Answer:
2. Step-by-step explanation: We have been given the numbers 28 and 42. First of all we find the lcm and hcf of these numbers.
3. hcf is the common factor among the above factors. And lcm is the product of common factors and the rest factors. Thus, we have.
4. Therefore, the ratio of lcm and hcf is 6:1.
