Given numbers are 42,51,519

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

The LCM of 42,51,519 is 123522.

Find LCM of 42,51,519 with Prime Factorization

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

3 x 14 x 17 x 173 = 123522

Therefore, the lowest common multiple of 42,51,519 is 123522.

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.

42 x 51 x 519 = 1111698

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.

42 : 1, 2, 3, 6, 7, 14, 21, 42

51 : 1, 3, 17, 51

519 : 1, 3, 173, 519

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 42,51,519, is 3.

Now, the common factors can be found like this.

42:2x 3x 7

51:3x 17

519:3x 173

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 = 1111698/(3x3)

LCM = 1111698/9

LCM = 123522

Thus, we can understand that the LCM of 42,51,519 is 123522.
