Word Problems on L.C.M.
- Find the lowest number which is exactly divisible by 18 and 24.
- Find the lowest number which is less by 5 to be divided by 16, 24 and 36 exactly.
- Find the lowest number which is more by 6 to be divided by 25, 40 and 60 exactly.
What are some LCM problems?
Solution
- A bell rings every 18 seconds, another every 60 seconds. Prime factorizations of 18 and 60 are.
- LCM is the product of maximum occurrences of each prime factor in the given numbers.
- So L C M 12,18 = 2 × 2 × 3 × 3 × 5 = 180 seconds = 180/60 = 3 minutes. So the bells will ring at same time again at 5.03pm.

So, the LCM of 8,12,16 is 48. No doubt, a manual calculation is a little much complicated, simply add the numbers into the least common multiple calculator and lets it do the remaining. Another method to find the lcm of the given data set is the prime factorization method.
How to find the LCM using the greatest common factor?
The formula to find the LCM using the Greatest Common Factor GCF of a set of numbers is: A factor is a number that results when you can evenly divide one number by another. In this sense, a factor is also known as a divisor. The greatest common factor of two or more numbers is the largest number shared by all the factors.
