Given numbers are 66,11,19,71,923

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

The LCM of 66,11,19,71,923 is 1157442.

Find LCM of 66,11,19,71,923 with Prime Factorization

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

11 x 71 x 6 x 1 x 19 x 1 x 13 = 1157442

Therefore, the lowest common multiple of 66,11,19,71,923 is 1157442.

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 11 x 19 x 71 x 923 = 903962202

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

11 : 1, 11

19 : 1, 19

71 : 1, 71

923 : 1, 13, 71, 923

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 66,11,19,71,923, is 1.

Now, the common factors can be found like this.

66:2x 3x 11

11:11

19:19

71:71

923:13x 71

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

11x 71 = 781

Therefore, the value for common factors is 781.

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 = 903962202/(1x781)

LCM = 903962202/781

LCM = 1157442

Thus, we can understand that the LCM of 66,11,19,71,923 is 1157442.
