How do you calculate HCF and LCM?

Last Updated: 18th February, 2020

The highest common factor is found by multiplying allthe factors which appear in both lists: So the HCF of 60 and72 is 2 × 2 × 3 which is 12. The lowest common multipleis found by multiplying all the factors which appear in eitherlist: So the LCM of 60 and 72 is 2 × 2 × 2× 3 × 3 × 5 which is 360.

Also, how do you calculate HCF?

The product of least powers of common prime factorsgives HCF. Division Method: Two find the HCF of twogiven numbers, divide the largest by the small number, then dividethe dividend by the remainder.

One may also ask, what is the HCF of 24 and 36? Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18 and36. Therefore, common factor of 24 and 36 = 1, 2, 3,4, 6, 8 and 12. Highest common factor (H.C.F) of 24 and 36 =12. To find Highest Common Factor by using Prime FactorizationMethod.

In this regard, how is LCF calculated?

One way to find the least common multiple of two numbersis to first list the prime factors of each number. Then multiplyeach factor the greatest number of times it occurs in eithernumber. If the same factor occurs more than once in both numbers,you multiply the factor the greatest number of times itoccurs.

What is HCF example?

For example, LCM of 10, 15, and 20 is 60. HighestCommon Factor (HCF): The largest or greatest factor commonto any two or more given natural numbers is termed as HCF ofgiven numbers. Also known as GCD (Greatest Common Divisor). Forexample, HCF of 4, 6 and 8 is 2.

What is meant by HCF?

The greatest number that is a factor of two (or more)other numbers. When we find all the factors of two or more numbers,and some factors are the same ("common"), then the largest of thosecommon factors is the Greatest Common Factor. Abbreviated"GCF". Also called "Highest Common Factor"

Is 41 a prime number?

All numbers that end in five are divisible byfive. Therefore all numbers that end with five and aregreater than five are composite numbers. The primenumbers between 2 and 100 are 2, 3, 5, 7, 11, 13, 17, 19, 23,29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89and 97.

What is LCM and LCF?

Now onto LCF. LCF (Lowest Common Factor)is when you find a number that goes into all four of the divide all four of the numbers by the number that goes into allof them. Finally, LCM (Lowest Common Multiple) theLCM is when you find the smallest number both thedenominators go into.

What is LCF in math?

Math Term Definition. Least common multiple (LCM)The least common multiple (LCM) of 2 numbers is the smallest numberthat they both divide evenly into. One good way to find the leastcommon multiple of 2 numbers is to multiply both numbers by1,2,3,4,5 and then find the first multiple that appears in bothlists.
