Given numbers are 820,163,934,455

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

The LCM of 820,163,934,455 is 5680149020.

Find LCM of 820,163,934,455 with Prime Factorization

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

2 x 5 x 82 x 163 x 467 x 91 = 5680149020

Therefore, the lowest common multiple of 820,163,934,455 is 5680149020.

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.

820 x 163 x 934 x 455 = 56801490200

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.

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

163 : 1, 163

934 : 1, 2, 467, 934

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,163,934,455, is 1.

Now, the common factors can be found like this.

820:2x 2x 5x 41

163:163

934:2x 467

455:5x 7x 13

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 56801490200/(1x10)

LCM = 56801490200/10

LCM = 5680149020

Thus, we can understand that the LCM of 820,163,934,455 is 5680149020.
