Given numbers are 66,81,447

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

The LCM of 66,81,447 is 265518.

Find LCM of 66,81,447 with Prime Factorization

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

3 x 22 x 27 x 149 = 265518

Therefore, the lowest common multiple of 66,81,447 is 265518.

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.

66 x 81 x 447 = 2389662

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.

66 : 1, 2, 3, 6, 11, 22, 33, 66

81 : 1, 3, 9, 27, 81

447 : 1, 3, 149, 447

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 66,81,447, is 3.

Now, the common factors can be found like this.

66:2x 3x 11

81:3x 3x 3x 3

447:3x 149

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 = 2389662/(3x3)

LCM = 2389662/9

LCM = 265518

Thus, we can understand that the LCM of 66,81,447 is 265518.
