Given numbers are 390,455,201

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

The LCM of 390,455,201 is 182910.

Find LCM of 390,455,201 with Prime Factorization

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

3 x 5 x 13 x 2 x 7 x 67 = 182910

Therefore, the lowest common multiple of 390,455,201 is 182910.

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.

390 x 455 x 201 = 35667450

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.

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

455 : 1, 5, 7, 13, 35, 65, 91, 455

201 : 1, 3, 67, 201

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,455,201, is 1.

Now, the common factors can be found like this.

390:2x 3x 5x 13

455:5x 7x 13

201:3x 67

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

3x 5x 13 = 195

Therefore, the value for common factors is 195.

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 = 35667450/(1x195)

LCM = 35667450/195

LCM = 182910

Thus, we can understand that the LCM of 390,455,201 is 182910.

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