Given numbers are 543,18,921

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 543,18,921 is 1000206.

Find LCM of 543,18,921 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

3 x 181 x 6 x 307 = 1000206

Therefore, the lowest common multiple of 543,18,921 is 1000206.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

543 x 18 x 921 = 9001854

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

543 : 1, 3, 181, 543

18 : 1, 2, 3, 6, 9, 18

921 : 1, 3, 307, 921

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 543,18,921, is 3.

Now, the common factors can be found like this.

543:3x 181

18:2x 3x 3

921:3x 307

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3 = 3

Therefore, the value for common factors is 3.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 9001854/(3x3)

LCM = 9001854/9

LCM = 1000206

Thus, we can understand that the LCM of 543,18,921 is 1000206.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 848, 17, 777
