Given numbers are 447,647,447

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

The LCM of 447,647,447 is 289209.

Find LCM of 447,647,447 with Prime Factorization

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

3 x 149 x 1 x 647 x 1 = 289209

Therefore, the lowest common multiple of 447,647,447 is 289209.

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.

447 x 647 x 447 = 129276423

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.

447 : 1, 3, 149, 447

647 : 1, 647

447 : 1, 3, 149, 447

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 447,647,447, is 1.

Now, the common factors can be found like this.

447:3x 149

647:647

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 = 129276423/(1x447)

LCM = 129276423/447

LCM = 289209

Thus, we can understand that the LCM of 447,647,447 is 289209.

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

• LCM of 809, 299, 860
