Exploring Numbers with HCF of 4 and LCM of 24
Understanding the relationship between the Highest Common Factor (HCF) and the Least Common Multiple (LCM) of a set of numbers is crucial for unraveling the intricacies of number theory. In this article, we will delve into how to determine three numbers that have an HCF of 4 and an LCM of 24. This exploration will not only enhance your mathematical prowess but also provide insights into SEO best practices utilizing relevant keywords.
Mathematical Introduction
The relationship between the HCF and LCM of numbers can be described by the following equation:
HCF(a, b, c) × LCM(a, b, c) a × b × c
For three numbers a, b, and c, given that the HCF is 4 and the LCM is 24, we can set up the equation:
4 × 24 a × b × c
This simplifies to:
96 a × b × c
Expressing the Numbers in Terms of HCF
Since the HCF is 4, we express the numbers as:
a 4x, b 4y, c 4z
Where x, y, and z are coprime integers (i.e., their HCF is 1).
Substituting these into the product equation gives:
4x × 4y × 4z 96
This simplifies to:
64x × y × z 96
Dividing both sides by 64:
x × y × z 1.5
Since x, y, and z must be integers, we need to look for combinations that match the HCF and LCM criteria.
Validating Combinations
Let's check several combinations of numbers that meet the criteria:
First Combination
a 4, b 8, c 12
HCF: HCF(4, 8, 12) 4
LCM: LCM(4, 8, 12) 24
Second Combination
a 4, b 6, c 12
HCF: HCF(4, 6, 12) 2, not valid
Third Combination
a 4, b 4, c 6
HCF: HCF(4, 4, 6) 2, not valid
Fourth Combination
a 12, b 8, c 4 (same as the first combination)
Conclusion and Validation
After checking several combinations, we find that the valid numbers are:
4, 8, and 12
HCF: 4
LCM: 24
These numbers satisfy both conditions.
By breaking down the problem, we understand the underpinning mathematical concepts and their practical applications. This knowledge can be leveraged not only in academic settings but also in real-world scenarios involving number theory, optimization, and data analysis.
