How to find the LCM in numbers?
Find the least common multiple (LCM) of two numbers by listing multiples
- List the first several multiples of each number.
- Look for multiples common to both lists.
- Look for the smallest number that is common to both lists.
- This number is the LCM.

What are the first 3 common multiples of 1 and 7?
Since 1 x anything equals that number . You will do the first 3 multiples of 7. Which would be 7, 14, 21.
Which is the least common multiple of two numbers?
For example, LCM (2,3) = 6 and LCM (6,10) = 30. For the least common multiple of more than 2 numbers, say a, b, c and d, it is the smallest integer that is evenly divisible by all numbers and can be calculated such that LCM (a,b,c,d) = LCM ( LCM ( LCM ( a,b ), c ), d ).
Which is the least common multiple of 11 33?
We can see, the first common multiple or the least common multiple of both the numbers is 33. Hence, the LCM (11, 33) = 33. Another method to find the LCM of the given numbers is prime factorization. Suppose, there are three numbers 12, 16 and 24. Let us write the prime factors of all three numbers individually.
How are numbers divided in the LCM method?
In this method, the given numbers are divided by the common divisors until there is no possible further division by the common number. The divisors and the remainders are multiplied together to obtain the LCM. 3. LCM using multiples
Which is the least common multiple for 4 and 6?
6: 6, 12 ,18,24,30,36,42….. From the above two expressions you can see, 4 and 6 have common multiples as 12 and 24. They may have more common multiple if we go beyond. Now, the smallest or least common multiple for 4 and 6 is 12. Therefore, 12 is the LCM of 4 and 6.
