How do you explain least common multiple?

How do you explain least common multiple?

The Least Common Multiple (LCM) of a group of numbers is the smallest number that is a multiple of all the numbers. For instance, the LCM of 16 and 20 is 80; 80 is the smallest number that is both a multiple of 16 and a multiple of 20. You can find the LCM of two or more numbers through various methods.

Does 0 count as a multiple?

Zero is a multiple of every number so (among other things) it is an even number. The number 12 is “a multiple of 4” or “a multiple of 6” but not just “a multiple.” (It is not, for example, “a multiple” of 5.) Numbers are multiples of something, not just “multiples.” Also, 6 is a factor of 12, not a multiple of 12.

How do you find common multiples quickly?

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 …

Is a multiple a 4?

Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, …

How do you teach the highest common factor?

The highest common factor is found by multiplying all the factors which appear in both lists: So the HCF of 60 and 72 is 2 × 2 × 3 which is 12. The lowest common multiple is found by multiplying all the factors which appear in either list: So the LCM of 60 and 72 is 2 × 2 × 2 × 3 × 3 × 5 which is 360.

What is the least common multiple of 3 and 5?

The Least Common Multiple of 3 and 5 is 15 (15 is a multiple of both 3 and 5, and is the smallest number like that.) So… what is a “Multiple”? We get a multiple of a number when we multiply it by another number.

How do you find the LCM of a given number?

LCM using repeated division 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.
