The highest common factor (HCF) and least common multiple (LCM) are used in daily life for various practical applications, such as simplifying fractions, calculating time intervals, and organizing schedules. For example, when baking or cooking, HCF and LCM can help determine the right proportions of ingredients or cooking times for multiple dishes. In logistics, LCM can be used to schedule deliveries or plan routes efficiently. Understanding HCF and LCM can streamline decision-making processes and optimize resource allocation in everyday tasks.
2 and 20 have an HCF of 2 and an LCM of 20. You could also use 4 and 10.
Chefs, carpenters, anyone who has to add, subtract or simplify fractions.
When we simplify fractions.
To find the LCM of these values, we need to factor out each term. 28 = 2² x 7 36 = 6 x 6 = 2² x 3² Select the prime factor with the highest exponent and multiply all the "available" primes. The LCM turns out to be: LCM = 2² x 3² x 7 = 252. Therefore, the LCM of 28 and 36 is 252.
Gcf you use when you are finding the greatest factor for the numbers. Lcm you use when you are finding the smallest multiple in the numbers factors
LCM is used to find the lowest common denominator in fractions HCF is used to reduce fractions to their simplest terms
If you are a teacher who works with 27 pupils and 18 pupils and
The HCF helps when reducing fractions. The LCM helps when adding or subtracting fractions.
In finding the LCM or HCF of two or more numbers
You would use it when adding fractions.
weighing scales
You use the LCM when you want to add or subtract fraction and then you can use the HCF to simplify the result. You may want to do this when budgeting: for example one quarter of your pay goes on rent, two fifths goes on food and drink, and so on. So how much of your pay is available for discretionary spending?
Use GCF instead of HCF. 6 and 30 would be those numbers...
2 and 20 have an HCF of 2 and an LCM of 20. You could also use 4 and 10.
