Given numbers are 222,21,222

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

The LCM of 222,21,222 is 1554.

Find LCM of 222,21,222 with Prime Factorization

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

2 x 3 x 37 x 1 x 7 x 1 = 1554

Therefore, the lowest common multiple of 222,21,222 is 1554.

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.

222 x 21 x 222 = 1034964

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.

222 : 1, 2, 3, 6, 37, 74, 111, 222

21 : 1, 3, 7, 21

222 : 1, 2, 3, 6, 37, 74, 111, 222

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 222,21,222, is 3.

Now, the common factors can be found like this.

222:2x 3x 37

21:3x 7

222:2x 3x 37

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

2x 3x 37 = 222

Therefore, the value for common factors is 222.

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 = 1034964/(3x222)

LCM = 1034964/666

LCM = 1554

Thus, we can understand that the LCM of 222,21,222 is 1554.

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