Given numbers are 395,530,647,647

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

The LCM of 395,530,647,647 is 27089890.

Find LCM of 395,530,647,647 with Prime Factorization

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

5 x 647 x 79 x 106 x 1 x 1 = 27089890

Therefore, the lowest common multiple of 395,530,647,647 is 27089890.

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.

395 x 530 x 647 x 647 = 87635794150

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.

395 : 1, 5, 79, 395

530 : 1, 2, 5, 10, 53, 106, 265, 530

647 : 1, 647

647 : 1, 647

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 395,530,647,647, is 1.

Now, the common factors can be found like this.

395:5x 79

530:2x 5x 53

647:647

647:647

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

5x 647 = 3235

Therefore, the value for common factors is 3235.

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 = 87635794150/(1x3235)

LCM = 87635794150/3235

LCM = 27089890

Thus, we can understand that the LCM of 395,530,647,647 is 27089890.
