What is the difference between lcm and hcf

The answer is 8. To see this, look at the multiples times table of 4: 4, 8, 12, 16, 20, 24, 28, The LCM is 20 because this is the first number that appears in both lists. The factors of 16 are: 1, 2, 4, 8, 16 and the factors of 24 are: 1, 2, 3, 4, 6, 8, 12, Answered by Joe C. Need help with Maths? One to one online tuition can be a great way to brush up on your Maths knowledge. Answered by. Step 2: Write the quotient below the numbers in the next row: 63 and Step 3: Now for the next division step, for which 63 and 81 will be the dividends.

Step 4: Think of a prime number again which divides the two numbers 63 and Step 5: Write the quotient below the numbers 63 and The next set of quotients are 21 and Step 6: Now, 21 and 27 will be the next dividends. Step 7: Repeat the steps till we get 1. Step 8: Multiply all the prime numbers at the left hand side of the bar and get the LCM of the given numbers. LCM of and is Solution: To find the HCF of and by the division method, we will follow the given steps: Divide by The obtained quotient is 1 and remainder is Make 38 as the divisor and as the dividend and perform the division again.

Here, the obtained quotient is 3 and the remainder is Make 12 as the divisor and 38 as the dividend and perform the division again. Here, the obtained quotient is 3 and the remainder is 2. Make 2 as the divisor and 12 as the dividend and perform the division again. Here, the obtained quotient is 6 and the remainder is 0.

The last divisor, 2, is the HCF of and Great learning in high school using simple cues. Indulging in rote learning, you are likely to forget concepts. With Cuemath, you will learn visually and be surprised by the outcomes. Explore math program. Explore coding program. The main purpose of showing the difference between these two numbers is to show the difference between a factor and a multiple. A multiple of a whole number is an integer that occurs in the timetable. Whereas, the factor of an integer is that number that divides the integer with no reminder at the end.

And to find the relation between the LCM and HCF of two different numbers first, we need to find the highest common factor of 15 and 18 which is 3. And the exact LCM of 15 and 18 is M and H. F is equal to the product of these two numbers. And to calculate the HCF by the prime factorization method take two random numbers and To calculate HCF by division method, simply follow the mentioned below steps:. For example, suppose two different numbers 12 and The greatest common factor of these numbers is:.

Several useful online calculators are available to find the greatest common factor. Most of the tools provide the following methods to check the highest common factor and least common multiple:.
