Quick Answer: Why We Use HCF In Real Life?

How is HCF used in real life?


: We use H.C.F.

1) To split things into smaller sections.

2) To equally distribute 2 or more sets of items into their largest grouping.

3) To figure out how many people we can invite.

4) To arrange something into rows or groups?.

Why LCM is used in real life?

So the LCM of all the timings is that time when all the strings will glow at the same time! So for all strings with timings between 1 to 3 seconds, LCM = 6. … These are the practical daily applications of LCM. So hail LCM!

Why do we find HCF?

When we have to find a number larger than given numbers, then we find LCM. If we have to find smaller number, then we find HCF .

What is the formula of LCM?

The Least Common Multiple (LCM) of two integers a and b, usually denoted by LCM (a, b), is the smallest positive integer that is divisible by both a and b….Formula of L.C.M.Formulas To Calculate LCML.C.M formula for any two numbersL.C.M. = \frac{a\times b}{gcd\left(a,b\right)}1 more row

What is the HCF of 12?

Find the highest common factor (H.C.F) of 12 and 18. Factors of 12 = 1, 2, 3, 4, 6 and 12. Factors of 18 = 1, 2, 3, 6, 9 and 18. Therefore, common factor of 12 and 18 = 1, 2, 3 and 6. Highest common factor (H.C.F) of 12 and 18 = 6 [since 6 is the highest common factor].

What is the full form of HCF?


How many types of HCF are there?

In short, the Highest Common Factor is expressed as H.C.F. Finding H.C.F. There are three methods of finding H.C.F. of two or more numbers.

Where do we use factors in real life?

Factoring is a useful skill in real life. Common applications include: dividing something into equal pieces, exchanging money, comparing prices, understanding time and making calculations during travel.

What is the importance of HCF and LCM?

L.C.M and H.C.F of two or more numbers help in finding out quick solutions and thus reduce time during examinations. The concept of L.C.M. is important to solve problems related to racetracks, traffic lights, etc.

What is HCF and LCM?

LCM : The least number which is exactly divisible by each of the given numbers is called the least common multiple of those numbers. For example, consider the numbers 3, 31 and 62 (2 x 31). … HCF : The largest number that divides two or more numbers is the highest common factor (HCF) for those numbers.

What is HCF of three numbers?

To find out HCF of three given numbers using division method, Step 1: Find out HCF of any two numbers. Step 2: Find out the HCF of the third number and the HCF obtained in step 1. Step 3: HCF obtained in step 2 will be the HCF of the three numbers.

What is HCF and LCM example?

For example, LCM of 10, 15, and 20 is 60. Highest Common Factor (HCF): The largest or greatest factor 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 4, 6 and 8 is 2.
