Given numbers are 73,75,30,21,215

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

The LCM of 73,75,30,21,215 is 3295950.

Find LCM of 73,75,30,21,215 with Prime Factorization

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

3 x 5 x 73 x 5 x 2 x 7 x 43 = 3295950

Therefore, the lowest common multiple of 73,75,30,21,215 is 3295950.

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.

73 x 75 x 30 x 21 x 215 = 741588750

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.

73 : 1, 73

75 : 1, 3, 5, 15, 25, 75

30 : 1, 2, 3, 5, 6, 10, 15, 30

21 : 1, 3, 7, 21

215 : 1, 5, 43, 215

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 73,75,30,21,215, is 1.

Now, the common factors can be found like this.

73:73

75:3x 5x 5

30:2x 3x 5

21:3x 7

215:5x 43

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

3x 3x 5x 5 = 225

Therefore, the value for common factors is 225.

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 = 741588750/(1x225)

LCM = 741588750/225

LCM = 3295950

Thus, we can understand that the LCM of 73,75,30,21,215 is 3295950.
