Given numbers are 419,533,689,815

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

The LCM of 419,533,689,815 is 9646609765.

Find LCM of 419,533,689,815 with Prime Factorization

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

13 x 419 x 41 x 53 x 815 = 9646609765

Therefore, the lowest common multiple of 419,533,689,815 is 9646609765.

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.

419 x 533 x 689 x 815 = 125405926945

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.

419 : 1, 419

533 : 1, 13, 41, 533

689 : 1, 13, 53, 689

815 : 1, 5, 163, 815

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 419,533,689,815, is 1.

Now, the common factors can be found like this.

419:419

533:13x 41

689:13x 53

815:5x 163

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

13 = 13

Therefore, the value for common factors is 13.

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 = 125405926945/(1x13)

LCM = 125405926945/13

LCM = 9646609765

Thus, we can understand that the LCM of 419,533,689,815 is 9646609765.
