What is an example of a LCM word problem?
Find the lowest number which is more by 6 to be divided by 25, 40 and 60 exactly. We find the L.C.M. of 25, 40 and 60. Therefore, the required number is 600 + 6 = 606.
What types of problems can be solved using the least common multiple?
Problems in which two different amounts must be split into (select) number of groups can be solved using the GCF. Problems with events that occur on (select) schedules can be solved using the LCM.
What are GCF and LCM word problems?
These word problems need the use of greatest common factors (GCFs) or least common multiples (LCMs) to solve. Mixing GCF and LCM word problems encourages students to read and think about the questions, rather than simply recognizing a pattern to the solutions.
What is the word LCM?
Definition of least common multiple 1 : the smallest common multiple of two or more numbers.
What is the LCM of 12 and 15?
60
Hence, the Least common multiple of 12 and 15 is 60.
How do you find the least common multiple of two numbers?
Therefore, the formula to find LCM of two numbers is, LCM of two numbers = product of two numbers รท HCF of two numbers. Note: The LCM of two co-prime numbers is equal to the product of co-prime numbers because the highest common factor of prime numbers is 1.
Why do we calculate LCM?
In math problems where we pair two objects against each other, the LCM value is useful in optimizing the quantities of the given objects. Also, in computer science, the LCM of numbers helps design encoded messages using cryptography.
What is the LCM of 25 and 10?
50
The LCM of 10 and 25 is 50.
What is the LCM of 15 and 9?
45
The LCM of 9 and 15 is 45.
What is the LCM of 7 and 9?
63
The LCM of 7 and 9 is 63. To find the least common multiple (LCM) of 7 and 9, we need to find the multiples of 7 and 9 (multiples of 7 = 7, 14, 21, 28 . . . . 63; multiples of 9 = 9, 18, 27, 36 . . . . 63) and choose the smallest multiple that is exactly divisible by 7 and 9, i.e., 63.
