How do you do LCM and HCF word problems?
Sometimes in such questions, the common remainder can also be asked. You can divide any of the numbers given by HCF (41 ¸ 10) and find the remainder to be equal to 1. L.C.M. of 2, 3 and 6 = 6 ; H.C.F. of 5, 10 and 25 = 5. Thus, the LCM of these three fractions will be 6/5.
What’s the least common multiple of 6 8 and 15?

Answer: LCM of 6, 8, and 15 is 120.How to find the least common multiple word?
To find the least number of trees, we have to find the least number that is evenly divisible by 6, 7 and 14. That is the least common multiple of 6, 7 and 14. Find the least common multiple of 6, 7 and 14. The least number of trees required to plant 6, 7 or 14 tress in each row is 42.
How to find the least common number of numbers?
The smallest among them is 6. Therefore, the Least Common Multiple (LCM) is 6. Using the lists to find the LCM can be slow and tedious. A faster way is to use repetitive division to find the least common multiple. Divide the numbers by prime numbers. If a number cannot be divided it is copied down to the next step of division.
Which is the least common multiple of 6 and 10?
To find the least number of people, we have to find the least number that is evenly divisible by 6 and 10. That is the least common multiple of 6 and 10. The least number of people in the marching band is 30. Two numbers are in the ratio 4 : 7.
When to use least common multiple or least common denominator?
Objective: I can find the least common multiple or least common denominator. Read the lesson on least common multiple if you need to learn how to find the lowest common multiple. We use the least common multiple when adding or subtracting fractions with unlike denominators. It is then called the least common denominator.
