How do you find the LCM of 2 numbers?

How do you find the LCM of 2 numbers?

Find the least common multiple (LCM) of two numbers by listing multiples

1. List the first several multiples of each number.
2. Look for multiples common to both lists.
3. Look for the smallest number that is common to both lists.
4. This number is the LCM.

What is the fastest way to find the LCM of two numbers?

How to Find the LCM – FAST!!!

1. Step 1) Find the GCF for the two numbers. For 18 and 30, GCF is 6.
2. Step 2) Divide that GCF into either number; it doesn’t matter which one you choose, so choose the one that’s easier to divide. Choose 18.
3. Step 3) Take that answer and multiply it by the other number.
4. Step 4) Celebrate …

What is the LCM of two numbers that have no common?

When there is no common factor for the given numbers, LCM is the product of the given numbers. eg. LCM of 2, 3, 4 = 12 as 2 is a factor of 4 but 4 & 3 are relative prime and hence the answer.

What is the LCM of 24 and 36?

72
The LCM of 24 and 36 is 72. To find the least common multiple of 24 and 36, we need to find the multiples of 24 and 36 (multiples of 24 = 24, 48, 72, 96; multiples of 36 = 36, 72, 108, 144) and choose the smallest multiple that is exactly divisible by 24 and 36, i.e., 72.

How do you solve for LCM?

One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

How do you find the LCM of the denominator?

To find the least common denominator, simply list the multiples of each denominator (multiply by 2, 3, 4, etc. out to about 6 or seven usually works) then look for the smallest number that appears in each list. Example: Suppose we wanted to add 1/5 + 1/6 + 1/15.

What is the least common multiple LCM of two numbers the LCM of two numbers is the of the shared by the two numbers?

The Least Common Multiple of two numbers is the product of the two numbers only when they are relatively prime.

What LCM of two numbers that have no common factors greater than 1?

The lcm of two numbers that have no common factors greater than 1 is the factors of the two numbers multiplied together.
