How is HCF and LCM used in daily life?

This problem can be solved using H.C.F. because we are cutting or “dividing” the strips of cloth into smaller pieces (Factor) of 72 and 90 (Common) and we are looking for the widest possible strips (Highest). Priyanka should cut each piece to be 18 inches wide . L.C.M. : we use find L.C.M.

What is the use of LCM?

The lcm is the “lowest common denominator” (lcd) that can be used before fractions can be added, subtracted or compared. The lcm of more than two integers is also well-defined: it is the smallest positive integer that is divisible by each of them.

How do we use HCF in real life?

Applications of HCF It is used to split things into smaller sections, to arrange something into rows or groups, to distribute more numbers of items to large groups, and to figure out how many people we have to invite and so on when we want to split things into smaller sections.

What does LCM and HCF mean in maths?

The Highest Common Factor (HCF) of two or more given numbers is the largest number which divides each of the given numbers without leaving any remainder. The Lowest Common Multiple (LCM) of two or more numbers is the smallest of the common multiples of those numbers.

Why is HCF important?

Why is H.C.F and L.C.M important? 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 the full form of LCM?

The least common multiple is abbreviated as LCM, defined as the least among the common multiples of the given numbers.

What is the GCF of 12 and 30?

GCF of 12 and 30 by Listing Common Factors Therefore, the greatest common factor of 12 and 30 is 6.

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 full form of HCF and LCM?

Answer: The full form of HCF is the Highest Common Factor and the full form of LCM is the Least Common Multiple.

What is HCF formula?

L.C.M and HCF Important Formulas H.C.F. of a given number always divides its L.C.M. To find the greatest number that will exactly divide x, y and z. Required number = HCF of x, y and z. To find the Largest number that will divide x, y and z leaving remainders a, b and c respectively.

What is a full form of HCF?

highest common factor in British English noun. the largest number or quantity that is a factor of each member of a group of numbers or quantities. Abbreviation: HCF, h.c.f. Also called: greatest common divisor.
