Given numbers are 455,311,447,447

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

The LCM of 455,311,447,447 is 63252735.

Find LCM of 455,311,447,447 with Prime Factorization

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

3 x 149 x 455 x 311 x 1 x 1 = 63252735

Therefore, the lowest common multiple of 455,311,447,447 is 63252735.

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.

455 x 311 x 447 x 447 = 28273972545

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.

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

311 : 1, 311

447 : 1, 3, 149, 447

447 : 1, 3, 149, 447

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,311,447,447, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

311:311

447:3x 149

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.

3x 149 = 447

Therefore, the value for common factors is 447.

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 = 28273972545/(1x447)

LCM = 28273972545/447

LCM = 63252735

Thus, we can understand that the LCM of 455,311,447,447 is 63252735.
